Hi richard,

It is a matter of prescaler: at low values of prescaler accuracy is better than high prescaler values.

Always subtract 1 from the calculated values because the timer starts counting at 0. Same applies to the prescaler (as far as I remember). So 149 and 29 in your last example should give the correct interval.
