It appears the game can make logs with 0.1 second incriment, by changing hotstats the way you mentioned before.
The new version of FAF-STATS can't be changed the way you mentioned before and log files with 0.1 second incriments are not read.
Would be nice to have them read.
Looks like when the log file gets bigger that about 10 mb, it can't be handled by the program. Is it possible to fix this issue?
1 second intervals are already large and if you make the interval any bigger to cut down on file size it only makes things worse.
(if you integrate mass rate in with 1 second step, you underestimate the actual mass income by a noticeable amount, enough to make data analysis problematic)
