My analysis for this position with SF looks like this:
[d]kq6/1p5P/rp1p4/1p6/1P2P3/5Q2/2K5/8 w - - acd 74; acs 3297; bm Qc3; ce 487; pm Qc3; pv Qc3 Ra2+ Kd3 d5 h8=Q dxe4+ Kxe4 Qxh8 Qxh8+ Ka7 Qc3 Kb8 Ke3 Ka8 Kd3 Ka7 Qh8 Ra3+ Kc2 Ra2+ Kb3 Re2 Qa1+ Kb8 Qf1 Re3+ Kc2 Re4 Qxb5 Ka7 Kb3 Rh4 Qe2 Rh3+ Kc4 Rh4+ Kb5 Rh6 Qa2+ Kb8 Qb2 Rc6 Qe5+ Ka7 Qd5 Rc2 Qe6 Rc6 Qe5 Rc1 Ka4 Rc6 Ka3 Rc1 Qb5 Ra1+ Kb2 Re1 Qa4+ K;

Sure looks like a perpetual to me. So despite the big score, it is a draw
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

After move 15 of this line a drawn position is reached according to Lomonosovs:
[d]1k6/1p6/1p6/1Q6/1P2r3/8/2K5/8 b - - 0 15
