But I found there a few ships where the times doesn’t match the results of the calculation (from circa 50 verified) and I want to know if they are simply wrong or if there is something else that I don’t understand.
I found this (at right side are my results):
The wiki might not be up to date on the T3 cruisers. Their rebalance patch was not that very long ago. And Tactical destroyers have 3 modes which should all afflict the time to warp differently. Maybe those are different in your calculations?
No idea about Sunesis and Avatar, though.
