Note: originally posted this under the resource discussions, I didn't realize this thread had been revived. Since this is a more appropriate place for this comment I've moved it to here and deleted it from the discussions. Very important and confusing topic to write a guide for. This has great info and tips but some of the wording is confusing and difficult to follow. If I may be so bold I'd make the following comments/suggestions. Method 2: First few sentences are clear, the rest is explained in a way that's too wordy for my liking and confuses me. But I do get how difficult it can be to explain these types of things. For example, "This answer is the possible number of districts of a particular type that can get a discount but you must subtract from this any districts of that type that have already been placed or finished" might be reworded to, Suggestion: "This answer, minus the number of placed/finished districts of a particular type, is the possible number of discounts available for new districts of that type", or something like that. Also in Method 2, you have at the end a note about updating the discount check, if this applies to both methods, I think it would make more sense to have it appended as a separate note rather than being part of Method 2. For example, that section would look like (with my above suggestion): Spoiler : [*]Method 1 - Look in the production screen, if the number of turns to complete a district is less than another district (apart from Unique districts and the government plaza), you are getting a discount. [*]Method 2 - Count up the number of districts you have completed, divide it by the districts you have researched. If the answer is below 1 then you get no discount otherwise round up the answer. This answer, minus the number of placed/finished districts of a particular type, is the possible number of discounts available for new districts of that type. [*]Note: If you go to place a district which you expect a discount on but are not getting that discount, you either need to finish a tech/civic to update the discount mechanism or you have calculated something wrong Some proofreading: "This means my average is 3+3+1+1=8. You have discovered 4 districts so your average is 8/4=2" --> Suggestion: "This means my average is (3+3+1+1) / 4 = 2." "This 2 means you get a discount on your first 2 of any district that you place". "So we can conclude that the average number of completed districts rounded up is the number or any type of district you can get discounted as long as the average is at least 1." Suggestion: or --> of ? Indeed, it is helpful to think about it this way. For some reason, when I first read "average" it confused me because to me I think of B/A as a ratio since we're comparing two different things (districts built vs district types researched), I had no idea what average you were talking about at first, but after thinking about it more, in this case the ratio also happens to be an average. Just a couple of weeks ago I was reading through this long discussion on this topic and it's very helpful to have a well written guide as this with excellent practical/tactical suggestions as well while I'm still learning to make use of this mechanic. Apologies for my criticisms and boldness with the suggestions, merely trying to provide some feedback I think would be useful but I really hope not to be insulting. Thanks again for this educational guide.
