So far, turning 20/20 for a couple of grips and start the run at 79/79 seems safe, as it turns to be 99 when it is needed.

Didn't done much runs, 'tho, so dunno if going more aggressive with turn-ins and starting with 69/69 can still be safe or not.

In your experience, what can be the lowest level to start but still safe for when things become harder?
