BtS 3.19 Ancient Era turns to Chop a Forest at different game Speeds:


3 Quick
3 Normal
5 Epic
9 Marathon


Notice that a Forest Chop at both Quick and Normal speed takes the same number of Worker turns (3).

Worker action lengths (in # turns) at Quick speed are defined by the Game to be 0.67 times the no. of turns taken at Normal speed.

From others more familiar with the relevant XML code, I understand that the calculation of the number of Ancient Era Worker turns to complete a Forest Chop in a Quick game is:

No. of Quick turns to Chop a Forest = 0.67 * No. of Normal turns to Chop a Forest = 0.67 * 300 /100 = 201 / 100 = 2.01 = 3 (rounded up).

The above calculation is incorrect due to the incorrect 0.67 coefficient. The correct coefficient is 0.66, since 0.66 = 330/500 = # Quick turns per Game/# Normal turns per Game. Using the correct coefficient of 0.66 rather than 0.67, the bug in the above Forest Chop turn calcution is fixed as follows:

No. of Quick turns to Chop a Forest = 0.66 * No. of Normal turns to Chop a Forest = 0.66 * 300 /100 = 198 / 100 = 1.98 = 2 (rounded up).

BtS 3.19 Ancient Era turns to Chop a Forest at different game Speeds (with a 0.66 Quick/Normal turn ratio):


2 Quick
3 Normal
5 Epic
9 Marathon


I do not know whether this bug exists in previous BtS versions like 3.13 or 3.17, since I no longer have these versions. This bug may also exist in Civ4 and Warlords.
