I think the main argument arizen here is the requirements of always bandaid fixing things whilst the issue could be resolved by fixing the source of the problem? Im sure thats whats trying to be said. Also I have got to admit one thing in saying this is that there is No doubt Dan can run these right gapped plugs of -11 (Factory settings) with splitfires coil packs attached to them is that no doubt dan has researched the right conditions for this to be operating in. Hence AFR's are most likely to be perfect: Too rich foul the plugs missfire due to poor connection (Hence regap) , too lean well sif you go down that path, And for the ""Modified"" non stock thats rubbish in a way as fuel and air are still added the same way to the combustion chamber if the afr is correct there should be no reason why you cannot run stock gapped plugs, Tuning would be another issue to why people go smaller gapped plugs but that said there Also has got to be a limit of a certain gap and heat range for what power to be produced. (contradiction to my previous comment) Maybe? But there is a limit on everything no matter what it is.

Im sure they have the money in the r+d on the issues ? Although i have got to say better ignitions systems ie: Splitfires or MSD ignition modules would help but are expensive and long term fixes for running smaller gapped plugs due to there ability to be able to produce a better spark These are most likely where the issues are caused by at the end of the day
