I thought this would be quite interesting, so I made a quick bot to scroll through existing BLID databases (daprogs, greek2me and BLGlass) and generate this graph:
It shows (depending on how green it is), the proportion of BLIDs there are in that segment.
Each bar represents 1,000 BLIDs, and it spans from 0-220k.
of course these aren't all blids, just the recorded ones
