NV5600 + 4:10 = ?rpm?

For those that have a NV5600 and 4:10 axle ratio with the stock tires, can you post up the rpm your turning at 60mph?
I have this combo and sit at about 1975rpm and wondered if that is right or not?
This truck has a lift in it and I believe it may have had a taller tire on it and wondered if maybe the speedo was recalibrated for the larger tires?

I never got it up to 70 to see what it was there.
Anyone else?

Excellent!!! Just what I was lookin for
1950 @ 60mph is what the calculator says I should be at so it looks like the speedo is right on.
