Help with priming sugar amount

[singybrue]

I have a Bavarian Hefeweizen I am getting ready to bottle.
I have a hair under 4 gallons in a plastic bucket fermenter, and I am estimating 3.5 gallons bottling volume.

I've plugged in the following numbers to 3 different calculators and get 3 different #'s back for the amount of corn sugar:
3.5 gallons at 67 degrees carbing to 3.6 vols

Northern brewer-5.5oz corn sugar
Beersmith-4.82 oz corn sugar
Brewers Friend-5.1oz corn sugar

Any suggestions/recommendations? Should I just go with 5 oz and call it good?

I don't think I'd carb to 3.5 volumes, that's bottle-bomb territory. Stick to 3.

I was just using the middle of the recommended carb volume range.
I guess my main question is which of these calculators have you found to be most accurate?

I've been using beersmith. When it asks you for the beer temperature, enter the highest temperature the beer has been to, not what it is currently.

For example, say I ferment at 62, and raise it to 68 to finish. Then I cold-crash it for clarity, so when I'm bottling the beer is 34 degrees. Use 68 degrees as beer temperature.

Thanks, Bishop. I fermented at 67/68, so I'm good there.
Do you find the beersmith sugar calculations to be accurate?
I usually keg, this will be the 1st time I bottle in a looooong time.

The carb levels in my beers have been fine going by Beersmith's numbers. No idea how 'exact' it is, but no complaints on any of them, either.
