Fossilize seems to be inaccuratly estimating current progress

[MissPotato]

Recently I had fully compiled the shaders for Deadlock and the first 80% was kind of fast. Taking exactly an hour. An hour later it was at 91%. An hour after that 95%. With the remaining 5% taking an additional hour and a half. The problem seems to be that the replay doesn't calculate total frames correctly. At 0% there the log states it was on frame 0 out of 162,056. However, by the time 100% rolled around this number grew nearly to be 1,101,139.

I know my computer isn't great, so I understand it takes a long time, it's just hard to estimate how long it'll be taking with the percent not even closely aligning with total time.

Manjaro Linux 6.10.6 kernel at time of processing
555.x GPU driver at time of processing
