Help Needed: Figuring out Accuracy in PoE 2

Hello, I have been playing a lot of ranger recently and noticed that the tooltip hit chance isnt right for ranged attacks (obviously, there is an accuracy drop off from distance). I wanted to figure out the accuracy formula to know exactly how much DPS I lose when im not close to my target. I went on a level 44 witch and equiped a bow, to check different accuracy rating numbers and how it impacted the estimated chance to hit. Similar magnitudes of increments in accuracy seem to make a bigger difference in PoE 2 than in PoE 1. Losing half your accuracy in PoE2 when you are right at the hit cap makes you lose more chance to hit than in PoE1. Adding to this, I specced Far Sighted (30% reduced penalty to accuracy at range) to my pconc character and instantly noticed a big improvement in map clear, probably coming from hitting more often to far away targets.

To add to this, the tooltip is also wrong*, in the sense that a big portion of enemies have bonuses to evasion. Some zones are very egregious, like the Dreadnought Vanguard(https://poe2db.tw/us/Faridun_Spearwoman this NPC has almost double the evasion, making her really hard to hit). Most zones seem to have mobs with at least 30% increased evasion. Even for a melee character that is barely capped on accuracy, this would lead to more misses than expected, and since the accuracy formula seems to be more punishing than in PoE1, this leads to a bigger DPS loss.

Does anyone have the exact accuracy formula and knows exactly how the distance drop off works in reaity? Is it no penatly up to 2 meters, and 9% per meter until 90% less? What would be an ideal accuracy for endgame on a melee character and a ranged character so you basically never miss?

Thanks in advance.
