The 10k cap was estimated (I believe someone took the code and showed it as 10k cap, they also had revealed teh 150 GR cap) But this was years ago.
150 is still a ways off. Whats the current max (don’t have the ability to see the solo boards right now), 135ish. At 135 you still need to increase your damage by 11x over current values. Rememember that current top runs are already running with near max stats gear. 150 still going to be a while solo.
