Is a 70 BI downswing still normal? But ok, it's only 250 games. How did it go before this, maybe you have chosen to show the graph from when the downswing began, maybe it had gone well before that? Then this graph shows things from almost the worst possible angle.
I like you have that small upswing in the beginning of the graph, and also a break even section in the middle and in the end. That is much better to have than none at all for the prospects
But I would probably move down if nothing else for psychological reasons, even if I feel I'm a bit hard cooked, but that's me. By moving down you achieve two things: the players are worse and if you lose even then because of variance, you'll lose less because of the lower buy-ins. You prevent yourself from tilting. And not try to chase the losses, because it's a new game setting, you can start from zero so to speak.
GL however you decide to do!
