same moves get rated differently depening on the game?

I've noticed that in openings the exact same move may be rated differently in different games

here are 2 identical games but in the first game Qf3 is a blunder and in the second one it's just a mistake

another example: 

2 games have Qe7 as great move, one has it as just best

2 have d3 as mistake, one as blunder

Perhaps the player ratings are a consideration?

I thought about that but it doesn't work out, it would make sense if at lower level the evaluation was less harsh but in the first example it's the opposite

also games 3 and 4 are both at 1300

another example: d5 is good in the first game, an inaccuracy in the 2nd and mistake in the 3rd grin

Might be some "fine tuning" of the algorithm in the time between games. A move's classification is judgmental, and the criteria sometimes change with time.

well, if those games were from different times, then the game review's algorithm might have been updated.

Was just thinking about the ratings actually, and how having 4 from inaccuracy to blunder seems too wide. I recall notations would only have 2 right? Mistake then blunder. Maybe also they can put something a little more forgiving instead, like “Risky” for something, that may be a bad move except it was a trapped that worked.

Nh3 is an inaccuracy in the first game and a great move in the second one 🤯

I encountered this a while back. In a game review, one move was suggested as best, with a positive evaluation of the position. The suggested move seemed strange to me and so I played the game through on an Analysis board. Here, the suggested move was considered a mistake, leading to a negative evaluation. This was just a few minutes after the game review, so it is unlikely that a software update occurred. 

So, the all-knowing stockfish is not infallible

It is not infallible honestly only (sometimes ) listen to it in openings but tbh stockfish is pretty dumb

And the fact that stockfish runs differently each time it "reveiws " a game it's like it's running a game on separate computers or something one of the mistakes people make is listening to stockfish every move

Iv been trying to not listen to stockfish recently when I review my games (I don't listen to it at all cause dumb but I use it sometimes) Im just trying to make it so I don't use it at all

The question is is it game review fault Or stock fishes fault or is it both ?
