SK-105A2: 183,000 x 4.4 = 805200.
183,000 x 1.3 [minimum multiplier for completing a battle] = 237900 - 183000 = 54900 + 805200 = 860100.
860100 / 291 battles = 2955 RP per match, which seeing your KDR, makes sense.
So 860100 total RP MINIMUM [with premium], 60% were victories, so slightly higher in reality.
At 3 vehicle spawns that’s 8867 RP per match BTW.
So yeah, without premium, I can see it taking you that many battles, but that research is above what it was years prior.
Maybe it was worse 1-2 years ago, but I remember way before than that being able to get over 10k rp on good games with lots of kills and now its very hard to go over 6k with premium
Those games likely lasted 20ish minutes.
You can get those games today, and get more RP.
The “issue” with matches today is everyone’s more skilled, higher skill = likelihood of faster matches.
I remembered playing with my 15cm Sig sfl at 6.0 or something. I killed 3 or 2 Enemy Tanks survived The whole round with The Tank and gained 1500 Research. Thats more than i earn in rea on 6.7
I lately spaded Giraf. It’s a rank 6 ATGM, a pretty bad vehicle, hard to get kills with it, and it took me 85 battles:
Spoiler
You can see I only gained 42.2k action RP (right side of the screenshot) and that was enough to spade it. In total this vehicle required 130k RP to get all the modification.
I use the premium account of course, so my RP is doubled. I understand that’s a huge help, especially when you spade vehicles (you will get key modifications two times quicker with a premium).
I also know how to play to get good RP. I know surviving battles is the most important thing. I also like to play this way, I like surviving battles. I play with 1 vehicle lineups (which is something I know most players don’t like). In my opinion the game is designed in a wrong way, and I would love to see second free spawn option on vehicles (third spawn would require a backup). The thing is, when I want to play a specific vehicle, I only want to play this one specific vehicle and nothing more. The game only allow me to spawn 2 times (one free spawn and second spawn using a backup). I use a lot of backups, every BP season I buy all available backups from the warbond shop. But even this way I can’t use a backup every time I die. I just don’t have enough free backups available. So I only use backups, when I have a good beginning of the battle and then I die. When I have bad beginning of the battle, I just change the battle, because it’s not worth to waste a backup item on this battle (it’s too risky). If I had a second free spawn, I would use it basically all the time, because I don’t care about the SL, so I don’t mind to die again and lose SL. So my only problem is the limited amount of free backups.
Unfortunately, if you want to progress in War Thunder in any reasonable speed, you not only need a premium account, but also you need to play the way to use the current RP system to your advantage. You have a very good K:D, but K:D is not as important as staying alive in battles. If you kill 5 enemy players and die after 5 minutes, you will get significantly less RP than if you kill the same 5 enemy players, but survive 10 minutes battle. That’s just how the system works. It’s mostly time-based nowadays.
