It's not pandemic related at all. They are doing it because games keep running later and later and people with families don't want to be out at a game on a school night until well past 10:00. Which is the reason why they are doing it in April, May and September but not in June, July or August.
Note, however, that they most certainly did not take your advice, unless you are going to argue that 6:30 is in the middle of the afternoon.
No one takes more credit for getting predictions right that didn't actually happen than you. You are like those guys on those old football tout shows that they used to have on television who would claim that their 5 star super de duper blockbuster lockof the week picks were hitting at a 93% rate on the season.
Although they probably found more suckers to believe them than you ever have.
