How does the SCORE CALCULATION FORMULA work?

[Jamers]

It says on the records screen something like:
Record=100+max(1,100-Game days)*Game Difficulty (1..4)
Hero level and quests completed: +2%

I've tried plugging in the numbers (w/o the +2% bonus) on the stats of the scores already in the top ten (programmers or just BS records or whatever) and nothing even comes close to their final scores.

Anyone know how this actually works? Is there a typo in the formula? The game is riddled with them due to sloppy translation.

Thanks!
