Spider Solitaire Win Rate

What is the maximum win rate for 4-suit Spider Solitaire, with random shuffle?

I consider myself an expert player.

 Between June 5, 2022, and April 28, 2024, I played 4,678 games, with 2160 wins.

That computes to a 46.2% win rate.

I suspect that a few of the games that I did not win, were in fact, winnable.

Therefore, I estimate that about 50% of 4 suit Spider Solitaire with random shuffle are winnable.

Note:  I am playing using Microsoft Solitaire & Casual Games, using unlimited undos, with random shuffle.
