Question about tubeless tire pressure for all the experienced users here:

At 176lb (presently 180lb, but i'll be bacl to 176 by the end of the month. Really) I generally run my clinchers at 110r/100f for 23s, 100r/90f for 25s and 90/80 for 28s. With tubeless, I am guessing at lower pressure, the sealant is more likely to seal instead of doing bukake all over my bike and me. Is there a general rule of thumb on how much lower i can go with tubeless, so that odds of sealing improve and yet rolling resistance doesnt get too high?

Thanks!
