Players used to post tons of question on it for years and answers often look like : "the important line is the green one" or " it's style dependant" [...]
But nowadays, players' styles tend to convert toward GTOish game plan. So, my question is : in this environment, in 6max nl (lets say nl200-nl500 game) what a solid winner's red line supposed to look like ? (could be theorical answer or exemple of crusher if you know what their graph look like ^^)

• going up a little ?
• break-even ?
• going down ? if so, what "lose" rate seems reasonable for you and what doesn't ....

My guess is losing red line is standard but I can't figure what rate is reasonable
