4,748,700 RP
The reason you don’t see a TT finished is due to playing multiple trees.
I’m level 63 with only the F5E as my highest unlock, but I’ve multiple nations ground out at WW2 and some to rank 5.
If instead, I went about it as ONLY ever playing swedish air -
(trawling thru my old posts):
Doing a super simplified calculation of “Take plane with highest RP cost for a given rank, multiply by amount needed to unlock next tier”. For the Ja37C, I just took its RP cost and the preceeding aircraft’s RP cost (260K + 350K).
Sweden, to unlock the 11.7 Ja37C without any top tier buy premium shenanigans takes at most 2.61 million RP - corresponding to level 35.
Variation of ±2 levels is possible with actually careful calculation paying attention to branches and realizing unlocking rank VII doesn’t take researching 4 J35Bs for 220K RP each J29F and J34 both only take 160K each, thus I’ve overshot the RP required by 120K here already.
Why calculate sweden? They got few aircraft and simple branch dependencies and not a lot of foldering. Foldering can reduce the RP requirement further, branch dependencies can introduce unpredictable RP requirements.
Getting JAS39C (absolute lowest plane in TT), it’s ~1.5m more RP rounded up. 1.5M more RP pushes us up to just under level 50. F18C is just half a mil, so not even 50.
Tanks I havnt calculated.
Another thing from that old thread:



They’re level 21 despite playing for nearly 6 days straight. Why? Because they only fly low-RP reward game modes (air sim, where you are capped at 2000 RP (+500 for landing) every 15 minutes) and aircraft (136% RP modifier).
I’m level 50 with 6 days in tanks, 6 days in planes (RB), 4 days in planes (SB) (total 16 days)
I checked some lvl 100 in my squadron. 13 days in planes (RB), 6 days in tanks (RB), 1 day in planes (SB). Total days: 20.
They have 4 days more played than me and are level 100. I have 11 days played more than that level 21 and I’m level 50.
Bit old, but still works for effect.
