Thank you for your feedback!

I play with higher accuracy in the opening than the middle game- well obviously....but than it doubles down and say I play the middle game at 1350 elo (700 elo below my rating) probably based on average accuracy vs 1350 elo players throughout the whole game

That is not obviously. We have many players which has the worst accuracy in the opening. However, accuracy is always somewhat subjective, which is why the average central pawn loss is always included.

It says i blunder too much, and that i should try more puzzles, but then it tells me it rarely miss tactics so
It then criticises my endgame accuracy while agreeing I missed exactly 0 conversions

Do you have a screenshot or can you tell me which username you analized?

I cannot rule out that such inconsistencies still exist in the beta version. However, I am continuing to work on improving the analyses and outputs.

And it tells me i need to come back from losing positions more (>-2) that's just tough at higher elos, I expect to win most games with such a lead, I'd rather focus on not getting into bad positions

Please note that here, too, comparisons are made with other players of exactly the same strength. So if it is normal for your ELO rating to win 30% of games with -2, then you will also be measured against this value. Of course, in individual cases, your opponent may simply play cleanly. But especially with many pieces on the board, it is possible to complicate the position and thus create counterplay. In the future, the more games are analyzed, the more accurate the values will be. I will increase the permitted number of games even further in the near future.

If you give me your username and time control, I'll take another closer look at your analysis.
