1150. Apparently, that’s negligibly better than a random number generator. Yay me!
I tried one of the online calculators, but I’m extremely skeptical of the estimates produced. I scored a 1380 when I put in my moves, but putting in complete nonsense moves produced an 1120.
I didn’t spend 5 minutes per move, but 50 minutes is a lot to ask in the first place. If you’re looking for a little random stimulation, try it out.
