OK....
1. We discussed that, yes. We may change it
3. We won't. We'll get like all the admins in on it and look at it with SF and stuff, take all of that into account and make the best possible decision....
4. IG that's right, but, if the last regular season games start in March, then they should be mostly completed by July/August.....at least hopefully.

The new rules (https://www.chess.com/news/view/official-nspdcl-rules-replaces-old-rules) are better and address most of my concerns. A few issues, though:
1. I wouldn't completely eliminate the rating requirement for a returning team. I would relax it, but if you eliminate it, a team that finds and recruits a couple young and rapidly-improving kids will be able to completely dominate in a few years. If the rating limit is relaxed but not eliminated, they can play together for a time, but eventually they'll get too strong and have to form new teams.
2. I wouldn't adjudicate any games on the Termination Date unless you can adjudicate ALL remaining games, or at least enough games to determine playoff qualification.
3. I would not rely solely on engine evaluations for adjudication purposes. A +5 position might usually be a clear win, but in a complex position, that's not always the case. Also factor in the strength of the players involved; a clear win for a 2000-rated player might not be so clear for a 900-rated player. It would be good to have a strong and experienced player involved in adjudications.
4. I would not determine the playoff schedule in advance. You might be able to start it in early August, but you might not be able to start until October or later if key games are still ongoing and have not reached a position that can be adjudicated. I would wait to announce the playoff schedule until you can actually start the playoffs. And again, I'd space the start of the games out by 1 month like in the regular season, even if that means the last round doesn't start until after the second season begins in 2021.
