for H2H with playoffs is the record book only until the playoffs start? or does it go to the end of the season? When will it be updated?
The league record book is live - it checks daily to see what the best stat totals are for a league.
During the playoffs, if you don’t have a game (bye, eliminated) you do not accrue stats. Teams cannot accrue stats when they aren’t competing.
Playoff stats are not counted separately from regular season stats. They are all stats from the season.
