Ignition Final volatile

Can anyone guide me as to why ignition timing could be jumping up and down continuously by 2 degrees? as seen at the bottom of my screenshot. It's sometimes smooth then randomly jumps up and down, only does it on boost.

Logging MAP at 40HZ
Logging FinalIgnition at 100HZ

Ah yes, sorry didn't realise knock retard on a single cylinder is taken into account in ignition final. Makes sense now, thanks.
