I'd suggest using a GTO approach to developing your ranges. Not sure if this will help but this is generally how I did it:

For each position (UTG to SB)
1. Figure out what hands you're comfortable 4b/calling off. This will work out to some X%.
2. Assuming that you don't want to fold more than 50% to 5b shoves, pick a range of 4b bluff hands that works out to about X% as well. This will be Y% of hands.
3. Figure out what hands you're comfortable calling a 3b with from that position. This will be Z%.

X+Y+Z% = Total Defense vs a 3b.

4. Assuming you don't want to fold more than about 66% of the time to a 3b (approximate GTO defense of 33%), then your total opening range from that position should be no more than 3x(X+Y+Z). Select an opening range approximately or somewhat tighter than 3x(X+Y+Z). (ie: total defense to a 3b of 8%, means you can open 24% from that position and not be exploited).

Anyways, this was generally how I was doing it. At least it's a good starting point.
That's a really helpful post Griffey, thanks a lot. That provides me with a good structure to follow which is something that I like to have and find really useful.

Just for clarification, where you say pick some 4bet bluff hands that work out to X% which we will call Y%...this is an independent %? It's not equivalent to X% of 4bet/call off is it?

So if my 4bet/call off equals say 3%, my 4bet bluff hands (Y%) can equal a different amount (say 6%) or is it equivalent in that it needs to be 3% as well? I hope I have explained that clearly enough.
