Optimal session bankroll

[Bricklayer]

Ok so I’m trying to figure an optimal amount of $ to risk per session based on a few things. My guess is I’m on the right track but with a possibility of flaws.

Here is the scenario...

50% of the time I lose my session bankroll. The other 50% of the time, the bankroll is multiplied successfully by 4x as a gain. For example, 1k turns to 5k for a profit of 4k.

So its like 80% chance to double your bank. Right?

This seems to be a coin flip scenario. You lose all or have your bank multiply by a 4x gain. One or the other. And it happens at a 50/50 rate.

So according to Kelly. Or are there other tools? What would the optimal session bankroll be on a given session? Is it 80%-20% for a total of 60% of total bankroll? Seems a bit much. Lol.
Let me know. Something seems fuzzy.
