If I'm counting right, the numbers per mod should be...
1, 2, 4, 8, 16, 32, 64, 128, 256, 512 for 10 mods; max possible is 1,023.
1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 for 11 mods; max possible is 2,047.
If it can go up to 2,047% then you've either skipped one of those but somehow made up the difference, or you've miscounted and there's 11 as Retry says.
Ed: Looking at your own .csv, yes, you've miscounted. There's 11 mods per group. There's 35 lines in the .csv; if you strip off the header line and the trailing blank line, that gives you 33 lines.
