TOC ladder stat's compared 2010 to 2020.

[Green]

On a positive note, I don't think the stats fully capture the popularity of the games - I completed 6 or 7 PBEM games in 2020 but I don't think I reported a single one.

You should still report these games, assuming you can remember the results. Reporting PBEM games is important as it builds up statistics on scenario popularity and balance. The more results, the more reliable the statistics. So it helps the community and it only takes a minute to enter the details.
