Joep, the delay measurement code you have at project\delay_calibrate
does not work well with clock rates such as 48MHz since some of the
calculation gets cut off. This could cause some of your deviation.

1/48000000*4 = 0.000000083333333333333333333....

but other clock rates work well:

1/20000000*4 = 0.0000002
