I noticed that as well. Definitely impacts both sides, so the question becomes "why?"
If I had to guess, I'd say it's a correction for vote counts that were WAY outpacing estimated total votes:
With 98% reporting, PA total vote count stands around 6.76 million
At the time of the first subtraction, with only 16% reporting, estimated total votes were already approaching 7 million (votes / eevp)
Also interesting is that once the subtractions are made, a new vote count "floor" is effectively set and remains steady throughout the remainder of the race.
Trump's vote share increases at -239k. that means they substract more from Biden.
I analyzed the data as well. it happens for both sides. the data is not reliable. sometimes the total votes go to zero.
