Uh! That's a typo. I meant 55k RP more to be accumulated but then again it's actually good to collect as much RP as we can before we exchange.
Once we hit the 100k RP mark we can exchange at any time. So better to accumulate more and than exchange all together.
And yeah, I do know that we can exchange the RP for WoF spins but I don't think it's really worth it.
I would always exchange them for the moment I hit the 100k mark (only reached it 1 time until now). You can win interest on it and it is kinda fun to start fresh again and to see how long it will reach before you hit 100,000 again. I also don't think it is really worth it to exchange RP for WOF spins, but it all depends on luck also.
