What does it matter? > (Although I still prefer 300 over 250 due to the 50/60 thing) I just want to point out that while a frequency of 300Hz has good dividers, it has a lousy period of 3.33... ms. It seems easier to make calculations with a period of 4 ms per jiffy (250Hz). The rest of the discussion I'll leave to others as I have no strong feelings either way. -- Paulo Marques
