LF help understanding graph/leaks and general advice

Hello again, you beautiful community, you!

Brief context/history: Fell in love with NLHE during that initial Moneymaker boom era, loved watching High Stakes Poker and all that jazz. Read as much poker literature as I could get my hands on and played a fair bit of 2NL/5NL as a slight winner/break even player. Black Friday hit and as a US player, the move to US facing sites was pretty miserable given all of the professionals being forced onto those sites and the recreational pool all but drying up entirely. Gave it up not too long after.

Now here I am more than a decade later, in 2025, finding myself falling back in love with the game. I had figured NLHE was more or less fully evolved and figured out around the time I left, just with understanding hand ranges, board texture, position, pot/implied odds and most importantly, HUDs/Databases. However, it seems another evolution took place while I was gone with GTO and computers have yet again poisoned another of my beloved wells. Thankfully at the stakes I play, GTO doesn't factor in all that much, but either way, I'm looking to learn and adapt to modern NLHE once more.

I understand the following data is of a very limited sample size and any advice given would be speculative at best, but considering it took me nearly two weeks of play to accumulate 8k hands, please set aside the limited sample size and provide whatever advice you can/are willing to anyway.

I've been playing 2NL on ACR and boy oh boy have things changed - the pool is predominantly reg infested with the occasional recreational and even the damn recreational players are somewhat competent - what a damn nightmare. I'm assuming the global sites still have "normal" 2NL that is filled with recreational players but I've gotta take what I can get as of now - still blows my mind that gambling on sports is totally fine but playing poker is degenerate somehow. >.<

Here's my ugly graph:

Please note that around the 4,500 mark, I did some research along with leak analysis and made some considerable strategy changes that seem to be performing much better thus far - namely by ironing out some horrifying play from the blinds and the fact that the button wasn't even close to my most winning position >.> So the first half of the graph and second half of the graph have some considerable differences in strategy application.

Also, I could have sworn the standard graphs had a descending red line on the bottom and an ascending blue line on top so I did what research I could on that and the consensus seems to be that the inverse CAN be profitable, but it's rare and far more difficult to maintain. I try to be reasonably aggressive but always thought of myself as a somewhat passive player overall, so I'm struggling a bit with understanding that and how I should proceed from here.

With my rakeback figured in, I'm currently running at 2BB/100. My ultimate goal would be to stop making massive mistakes that crush my winrate and land somewhere in the 8-10BB/100 at this stake, with a large sample size.

Here is my most recent leak analysis from the full 8.3k hands:

Far as what I think I should be looking to improve on:
-Tighten up my range in general, especially my raising and 3Betting range - especially from the blinds.
-Fold more on the flop with my low equity hands or when the board texture doesn't connect well with my perceived range.
-Fold more on the turn when the above is also true OR when I do wish to continue as the aggressor, mix in more turn checks with the bulk of my medium strength hands - I think I have a tendency when IP and sensing weakness to proceed too aggressively with thin value/bluffs against player types that aren't folding enough and just end up owning myself.
-I'm not entirely sure about River - I catch myself making both good folds and bad calls and I think most of my troublesome rivers are a symptom of poor flop/turn play, especially turn decisions.
-Lighten up on my blind stealing a bit.
-3B from blinds less, call more, though not too much more. I really struggle with ever wanting to call from SB when I feel like 3Bet/Fold works out better but it seems I'm mistaken.
-A little too aggressive overall, but making the above adjustments should trim that back some.
-Need to improve that blue line big time, but I think improving my flop/turn play should help there a good bit.

Am I way off on any of that or does it seem like a decent blueprint to move forward with?

Really, REALLY appreciate any of y'all willing to take the time to read through all of that and provide some insight and advice. Thanks very much - cheers!
