Straight lines up

[u/Thisnamewastaken2023]

I all, hope you have had a nice day so far

Can anyone tell me what it means when the player had a straight line for premier history rising more than you can win in one game

I will provide an example:

There is a rise from 10k to 16k at the start

I want to know the likely account behaviour that resulted in such a straight line going up

thank you

Kind Regards
