The gutters have been widened by 3-4 feet, at least

and I'm back... again

I don't know how I should digest to the fact that I can take several months off and get roughly the same daily high score.

Either I am massively skilled (the most likely) or the score is low enough that it is easily achievable with little practice. Actually, it must be the former, as I have 40.75 hours of bowling practice. It would take anyone else a whole work week to get to my skill level. So, massive skill it is.
