Remember, this is trial and error but you are very close. Once you get that dialed in, might begin increasing spark at lower kPas to get more low accel pep. The spreadsheet merely provides a starting point.
The reason I'm not getting knock at 100kPa at higher RPMs is I don't get 100kPa at higher RPMs, it only goes up to 90 - 95.
