Ideally the measurement should be to the G string saddle on nearly its minimum adjustment (ie towards the neck), nearly as it will allow a little room for error. The other strings will need longer string runs to intonate properly.
@dajaphonics take a look down the neck and see if it looks straight, or has a concave or convex bow. If someone has been adjusting it but doesn't really know what they're doing then it might be as simple as loosening the trussrod to get some bow back in the neck, and give you some string relief.
The neck wants to be a little concaved at the front, as if the headstock is pulling forwards, this will allow your strings to oscillate freely. If it's already got some bow then, as mentioned before, it might need a neck shim to angle the neck forwards.
No need to worry about measurements just yet.
