How does the third report work (player abp/dbp for dates in range)? Not to criticise as this is a fantastic thread and always look forward to seeing the new release - but it seems a little inaccurate... Or at least, not comprehensive.
The third report is for only the top 30ABP & 30DBP players. If some of those players don't gain any BP during the period they will not appear on that weeks report. That is how there will be less than 30 players on that report.
