Used in the XP tracker, to convert CRs to XP reward amounts. The format is 17 lines, comma-delimited. Each row is the xp for a different level - there are 17 rows because the first row combines levels 1-3 (so, row 1 corresponds to PC levels 1-3, row 2 = PC level 4, etc.) Column 0 is the starting CR for that row - for that particular party level, anything less than the start counts as "too weak" of an encounter, and should be dealt with on an ad-hoc basis. (these are CRs 8 levels lower than the party level.) Columns 1-9 contains enough data to extrapolate out the rest of the table - I could have left out a bunch of columns for the first few rows, but they stayed in to make coding things easier. The extrapolation from there is double the XP from CR - 2 (and if that's not there, double the xp from (CR - 2) - 2). This theoretically could continue forever, but there's a "too strong" limit put on XP rewards (8 levels higher than the PCs) to correspond with the "too weak" limit.
