I don't think that applies any longer:
> Additionally, players in Diamond, Master, and Grandmaster tiers that have not completed 5 matches in 7 days time will lose 25 SR every 24 hours, until they reach 3000 SR or complete the requisite number of matches. Playing a match now increases the time till decay by 36 hours. As of Season 18 SR decay was removed.
myspeld would have been barely Diamond, so he might have thought he needs to play at least 5 competitive games per week.
