Many people don’t do this, I think.
I always pump to max (120 psi), clean the tyre and roller with rubbing alcohol, tighten the roller until it no longer skids when I jerk the wheel back and forth with my hand. There’s hardly any wear on the tyre this way. Also, having softer/stickier rubber is important, whether it’s a special indoor trainer tyre or just a totally slick and grippy race tyre (Continental Ultra sport 2 works).
