pickup placement

[brandinstroy]

Do any of you guys know the 60's pickup placement for a 33" scale?
Is there some type of calculation to determine where this placement is depending on scale length? If not there should be just like there is for fret positions.

This is what i have come up with.

Neck Pickup Placement 82.14% of the scale length from nut
Bridge Pickup Placement 92.86% of the scale length from nut

For 34"
Neck: 27.9267"
Bridge: 31.5724"

Does this sound about right?
