It has been known in exceptional cases for the securing nut to come loose due to the poor machining of the crank shaft splines. Phil has the rotor splines machined undersize and then finishes them off by hand to exactly match the crank it is being fitted to, so they become a matched pair.
If the cranks were machined to any decent tolerance this would probably not need to be done. exceptional  - I wouldn't class a 10% failure rate of the PB kit as exceptional? Sorry but the 2500 (?) original Centa to crankshaft fitments as carried out by MMC never had a 10% failure rate of the nut coming undone and this nut was only ever tightened to 170lbft.
