ozonated oils

Hi People I have a questions about POI Potential Ozonoid Index (i think that is correct?).
As I understand when an oil has been fully ozonated, it produces an ozonoid. Does anybody have a chart or know which oils produce the highest ozonoids. I have heard Safflower, sunflower and flaxseed oils are very high (i hope I have the terminology correct. Please correct me if I'm wrong?). Also Is a high POI oil more difficult to make and is it necessarily more beneficial in all situations. Or what situations can they be more beneficial than ozonated olive oil which has a lower POI. Thanks.
