Once again steve your input is spot on.A drip or stick check , done accurately takes quite a while.Most stick checks are pretty rough affairs and unless the aircraft attitude is measured very accurately and fuel is not sloshing around (from wind, pax movement, loading unloading holds etc) is rather a crude confirmation that you have roughly the right fuel.
PS. note that there can be quite a difference between uplift SG and that in tanks.
