MythBusters!
I think I've read at least 4 times now from almost every team member how "highly inefficient" whipping is compared to working a GH. And were using a quote taken out of context from DaveMcW:
"It is always inefficient to kill a citizen working a mined grassland hill.
At size 6, it becomes inefficient to kill off a mined plains hill.
..."
I have great respect for his posts too, but I've had strong doubts about this one. Our blind faith in this alleged myth is poisoning our decision making.
Our empire is working only about two Gmines right now (we only have 3 complete!) and we've been whipping pretty freely, so if there's poisoning I'm not sure we've seen it yet
Let me define the myth : "You are always better off working GH instead of killing a citizen no matter what size your city is! Even if you have a granary!"
Not only is this a myth, but in most cases, it's actually the opposite. It's more efficient to whip even if you DON'T have a granary.
First off, his use of the word inefficient refers to the break-even point for total hammers. So 30 hammers received instantly from slavery is considered equal to 30 hammers gathered over 10 turns. This can be far from true. It is often HIGHLY efficient to have those hammers 10 turns sooner. However, I'll give him the benefit of the doubt and put NO value on early hammers. For example, let's say you have 1 turn left on a Library and
whip it. You don't get the library any sooner.
Sure, the analysis has to include the utility of having the whip-hammers now. The analysis also needs to take place well after the whip, so that the un-whipped population has time to show its value. The size of the happiness cap is also relevant. Neglecting any of these factors leads to an unbalanced analysis.
But that's not the biggest problem with this myth. It only applies to the case where you are working a GH with your very last food. (i.e. your city is now stagnant). The myth holds true for this one specific case where your city would need to grow back at +1 food. An only in the rare case where there is no value to getting your hammers early.
So the key to efficiency is related to the excess food/how fast you can re-grow.
If you have a granary, and if after you kill a citizen, you have only +2 food, it is still more efficient to whip!
Common Example: with granary, 36/72 food: You're working Corn + minedGH. Building a settler on marathon speed with 90 hammers to go (10 turns).
Compare 5 turns later....
No whip:
you would have no settler and still have to wait 5 more turns.
With the whip:
You have already re-grown to size 2, you've had your settler all this time, AND you've been building something else (at 1 hammer/turn)
Myth...Busted!
This example has a fully-improved city whipping at size 2, which is the most efficient size for whipping (fewest food to grow new population to convert to hammers). That's pretty artificial. You can get successive settlers out faster with 1-pop whipping such a city. You can also do that with successive settlers 2-pop whipping a similar 4-pop city *if* you have both Gmines and Gfarms available. By the time you get to size 6, at normal speed with a settler at 70/100 and a half-full food box and enough Gfarms and Gmines, whipping can get out settlers turn 1, 5, 11 and 17 compared to 2, 7 13, 18 without whipping... but there's 27 turns of whip unhappiness stacked up and that becomes limiting soon.
All the above pre-supposes settler spam, which have the benefit of being able to whip multiple population. For spam of 35 axes, whipping is poor because you can only whip one 30 population at a time, unless you can contrive to get at most 4 hammers of overflow. Spamming something like maces is easier, but the happiness cap is a critical factor in the length of time that constant whipping can stay ahead of non-whipping.
There are secondary effects with whipping or not - you have to pay more maintenance for larger cities, but having more population is useful in a some AI interactions, or bulbing techs.
Whipping does require more improvement infrastructure, because you need to re-grow on food tiles and want to work mines at the target size. This is where tile-sharing shows its strength. In theory, Delhi and PigGems could run whip cycles half out-of-phase with each other. While one is re-growing the other is using the mines.
