It is of course right and proper to pay attention to our teachers - to let them explain the rules - and to follow those rules when working the pedal board.
It might however be useful to know that there is a sub-set to those rules, and it may assist you to see them set out.
subset rule (i) Maintain note accuracy and rhythm.
subset rule (ii) Refer to rule (i)
subset rule (iii) If possessed of short lower leg and long upper leg, shift your bottom to the back edge of the bench, invest in 1.5 inch heels and follow rule (i)
Subset rule (iv) If possessed of long lower leg and short upper leg, take care not to jam your right knee between middle F# and the underside of the key shelf, then follow rule (i)
Subset rule (v) If, as on one of 'my' organs you have a straight - flat pedal board, and that it is offset to the left about one and a half keys, then any way you can reach bottom C ,short of poking at it with a stick, is the right way, as long as rule (i) is obeyed.
[If you play the pedals without shoes on, at some stage you will crack the little toe of your left foot on bottom Eb. This is absolutely guaranteed. This will then affect your ability to obey rule (i), resulting in you being taken out to the church yard and ritually flogged.]
subset rule (vi) If your Sunday morning service follows on from a particularly heavy Saturday night, settle for a nice gentle, wooly, slow-speaking Bourdon. This should obscure the fact that your feet have a mind of their own and that in certain circumstances, a 13/5 rhythm could be almost acceptable in the key of Kb.
As Douglas Bader quoted from somewhere or other,"rules are for the obedience of fools and the guidance of wise wo/men". Just so long as you obey subset rule (i)
Good luck
