Here is an explanation ... training works the same as build bonused ... of course you don't get help for training though ...

Well, the first two training pictures show a yellow asterix besides the training time, the last two don't (there it is besides the gold amount needed).

This usually indicates that there is a temporary global bonus for the training time, which you can see when hovering with the mouse over such an asterix.

Edit:

And in the stats, that simple "Bonus" line is missing in the second ss.
Also, your last training session has more amount of warriors available, why the rss amount also increased I guess.

But you are right that the numbers do not really match, even for the increased amount of troops by roughly 8%.

Have a calculator for training time. When plotting your stats and information I get that your first one is off. That is: it is faster then it should be. (At least from the looks of it)

From Jan. 1st

• 1 607 319 T4 should have been 18w 5d   1h but is 17w 6d 3h
• 1 607 319 T6 should have been 54w 0d 10h but is 53w 1d 8h

From Jan 8th the times match the ones in my calculator.

As explained higher up, different bonuses and boosts are treated differently.

If one add 25% to the total stats number from the Jan. 1st session, one get the time you had (17w 6d 3h).

You have repute Mentor in the stats from Jan 8th, but not in the ones form Jan. 1st.

So: could you have gotten repute on Jan 1st after you took the screenshot of your stats?

- That would have given you +25% in generic training stat numbers and would also have given you the exact training times you had on Jan 1st.

Put another way. Numbers from 1st are off, though I bet you wish it was the other way around ;)
