X+Y+Z = 5.1%. Opening range is 3x(X+Y+Z) = 15.3%. Even if I tighten that range up to 13%, we are still opening 77+,A8s+,K9s+,QTs+,JTs,ATo+,KJo+,QJo and that just seems quite a wide UTG range.

Have I gone wrong somewhere?

EDIT - I posted this before I read above post. I will work on it (I'm obviously 4bet bluffing too wide) and re-post w/ new ranges.
That's the right approach, but yah I agree your 4b bluff is too large vs your value 4b, so you'll be folding a ton to 5b shoves. And if ppl aren't 3b UTG opens that lightly, you WILL get shoved on a lot, so that's also something to consider.
