Session XP tracking tool

I devised a nice sheet to help players track experience during each gaming session. One of the fun things we are trying right now is to deduct 100 XP from a players potential session experience pool for each critical miss that is rolled by that player. Note: Final session XP will never be negative because of this and players do not deduct XP from their processed character. All deductions happen prior to level processing. Here is an image of the sheet.
