Re: Temple Overflow
I think BLuBMuZ was suggesting (at some point about a page back now) gaining from the temple double-speed bonus by overflowing twice as many hammers from a chop.
If that's the case, then what he is suggesting does not work.
In fact,
the opposite happens.
A Baseline Example
Let me give a baseline overflow example that gets capped off.
A Warrior costs 22 Hammers. Whipping will give you 45 Hammers.
If you play foolishly and whip the Warrior with 0 Hammers invested into it, you will only get 30 Hammers. That's like getting a pre-Math chop when you already know Math: a pretty bad thing. In this example, assume that our city is working Food + Commerce squares, such that the only Hammer is produced (the Hammer from the City's centre square). So, we'd have 30 + 1 = 31 Hammers - 22 Hammers = 9 Hammers of overflow.
That seems pretty straight-forward.
Now, let's complicate things with reality.
Overflow is capped at THE COST of the current item being built. Again, that sounds pretty straight-forward.
Let's use our Warrior example again, but this time, we'll build the Warrior for 1 turn. Again, we're just going to work squares with our citizens that give us Food + Commerce, so the only Hammer that we'll get is from the City's centre square.
After one turn, we'll have 0 + 1 = 1 Hammer invested in the Warrior. Very simple stuff.
Now, on turn 2, let's whip. This time, since at least 1 Hammer was invested in the Warrior, we will get the full value of a whipped person: 45 Hammers.
1 + 45 = 46 Hammers.
Now, how many Hammers will overflow? 46 - 22 = 24 Hammers. So, we'll get 24 Hammers in our next item in the build queue, right? No! The "capping" maximizes out at the cost of the current unit being built. The current unit being built has a cost of 22 Hammers. So, since 24 > 22, 22 is used as the overflow value. What happens to those extra 2 Hammers, 24 - 22 = 2? They get lost permanently. Gone. Vanished. Caput!
Okay, that's fine, it was only 2 Hammers. We can live with that amount. If you need to whip 2 Warriors quickly, you can invest 1 Hammer for 1 turn and then get 1 fully-produced Warrior.
The next turn, you will get 22 Hammers of overflow + 1 Hammer from the City's center, giving you 23/22 Hammers in the Warrior. That'll give you a second Warrior, with 23 - 22 = 1 Hammer of overflow. Very basic stuff. 2 Warriors can hopefully fend off whatever Barb unit was thrown at you. Had you "waited" until the last moment to whip, such that you had to whip when you only had 0 Hammers invested in the Warrior, you'd only have gotten 30 - 22 = 8 Hammers of overflow into the second Warrior. If the first Warrior had died, you'd be crying. So, don't whip an item that has 0 Hammers invested in it!
The Temple Example
What was the point of all of that talk? Get on with the lesson, already!
You'll quickly see that this info was useful.
Let's throw multiple factors into the mix.
Let's say that you have a Temple which costs 120 Hammers. If you whip the Temple and chop a bunch of Forests, such that you will have 240 Hammers, you'll complete the Temple and get 120 Hammers in overflow, right? Right? Ummm, I hate to break it to you, but, maybe not right.
You see, if you are Spiritual, the actual Hammers that you need to invest comes to 60 Hammers. So, if you've got 240 Hammers invested, 60 will be used up to complete the Temple. 120 Hammers will overflow, though, right? Nope! Only 60, the cost to YOU, will overflow. Yikes! You just wasted 240 - 60 - 60 = 120 Hammers THAT CANNOT BE RECOVERED! They are GONE FOREVER! Oops!
Now, let's complicate things further. What if you had a Forge. Or, instead of a Forge, you were running Organized Religion and the current city had your State Religion in it. Well, it wouldn't cost you as many base Hammers to complete the Temple.
In fact, it would cost you exactly:
120 Hammers / 2.25 = 53.33 Hammers to complete the Temple. The game probably charges you 54 Hammers, but it's hard to tell.
What is easier to tell is how much overflow you get, as you can see the integer value on the next turn. So, how much overflow will you get as a Spiritual Leader who is running Organized Religion with their State Religion in the city?
Assuming that you chopped a ton of Forests, such that you once again have 240 Hammers invested into the Temple, the overflow will be calculated as: 120 Hammers / 2.25 = 53.33, which gets floored down to 53 Hammers.
So, now, you've invested 240 Hammers, while only getting 240 - 54 (or 53, hard to say) for the Temple - 53 overflow = 133 to 134 Hammers WASTED! Gone! Gone forever! Never to return!
Summary
So, that's why it is a VERY BAD IDEA to try and overflow from a Temple into another building with a Forest chop--we'll probably almost certainly waste Hammers, instead of gain them.
Confusing Display
Now, the further truth is that the DISPLAY is confusing. If you'd actually invested 240 Hammers, they would appear as 240 * 2.25 = 540 Hammers, of which only 53 would overflow.
So, it is hard to tell with these Temples exactly how much overflow you are going to get. It doesn't help that some values get floored differently from what's displayed.
When should we whip a Temple then?
If we want to whip a Temple as a Spiritual Leader running Organized Religion, the best time to do so would be after only a couple of turn after you invested some Hammers into it, or as few as 1 turn of Hammers invested into it. Say, that we'd invested 9 Hammers on our first turn (from working the City Centre, the Grassland Copper, and the Plains Hills River square) which got multiplied by the 2.25 bonus to equal 20.25, which gets floored to 20 Hammers.
On the next turn, you'd see 20/120 Hammers invested. Whipping 1 population point would list us as having 121/120 Hammers invested. Assume that we are still making those same 9 Hammers, which gets displayed as putting 20 more Hammers into the Temple.
On the next turn, we'd only get 9 Hammers of overflow. Shouldn't it have been 10 Hammers? Well, that's where things with floors aren't accurate between the values displayed and the actual values that get calcuated behind the scenes. Ah, well, a loss of 1 Hammer that we thought we had but really didn't have isn't a big deal.
So basically, you can whip a Temple at any time, but if you whip it when it is almost complete, and if your citizens are working Hammer-heavy squares, you might not get all of the extra Hammers overflowing. No real difference from whipping any other building, actually.
So, what's the big deal? Well, we don't want to CHOP into our Temples, if we can help it, as that huge excess of production all at once, especially when the Temple is almost complete, can easily work out to a loss of Hammers, due to the overflow capping effect being combined with the capping effecting taking into account production bonuses (a max overflow of 53 Hammers on a 120 Hammer item isn't a lot of overflow--that's almost a full Mathematics-based Forest chop!).
