On a solitaire app. there is a feature that keeps statistics. Four separate times now I have reached a success rate between 42% and 42.5% over 1000 games.

I have noticed that my success rate does increase over time and the number of games played. Would, at some number of games I reach a 50% success rate?

If you graphed it out with success over the number of times played what would the graph look like? Graph (note, the graph is for comparison purposes only. The data has no meaning in this discussion) or would it be reversed or a bell or what?

PS this is not homework. I have already completed that, including mopping the floors.
