Working the math is more reliable than whatever the tach and speedo may be reading at a glance, both lag actual RPM and MPH. No slip in a manual gearbox, and the tires don't grow.
@ 6250 RPM
1st gear 46 MPH
2nd gear 65 MPH
Probably does read 42 MPH at the shift, but the car is going 46 MPH @ 6250 RPM unless the clutch is slipping.
Wasn't a glance nor lag, I know my car and it's nowhere near the speed the calculators show at redline. My speedo is dead on with GPS speed.
There's also no way there's THAT much lag with the speedo.
