If there are any %'s greater than 100% (which can happen in threaded merges) they will cause misalignment, but I think that's a reasonable bug to leave?
(Perhaps to be fixed formally by a merge method that has a kwarg for parallelism factor that does auto division when merging, etc. but that's another issue)

Just bumped the patch. It would be nice to get this out

[IanButterworth]

Bump. I think about this every time I see a report now 🙃
