When the game is started, configuration says:
"Receives xx seconds per HOUR"
That should say "per minute", to be in line with the above one. Sorry about that, I'll get that fixed.
Before that change, boot time was calculated a a percentage of the unused time per turn
Unfortunately that feature didn't work out, likely because it was very complex and took a lot of work to get working right. Hardly anyone used the old banking boot system, it was used in less than 0.1% of games. So it was upgraded to a new method which is much easier to understand and use.
