I've done a few 1" to 1.25" tall small knives lately. I put on the 4.5 degree and grind until I hit the spine. I'll cheat the bubble towards the near line or the far line on the gauge depending if I need more at the edge or spine, but I'm not changing degree wedges during the initial grind. I only use the jig for the initial grind pre-HT. After I set the bevel, I'll do the rest freehand. I only set the bubble once per knife.
Don't forget it does Clips very very well too!
