Consistent with previous reports, the detergent system was found to have the largest impact on LSPI frequency. Furthermore, once a balanced detergent system was identified and its LSPI impact was minimized, the effect of other additives, ash-containing as well as ashless, became apparent. In order to develop a robust additive package that maintains performance in critical bench and engine tests while offering optimal LSPI protection, consideration must be given to the impact of all lubricant additives not simply the detergent type and treat rate.

Wish I could see the paper, I'm very curious what they have to say about ashless additives.
Also surprised they didn't mention sodium in the ash-containing category, one additive manufacturer claimed it was a very aggressive accelerant for LSPI in the presence of calcium.
