Regarding point #4 I wouldn't go above 100 W coil under NO CIRCUMSTANCES!
I described in my earlier post in conversation with Peter Terren my experiment "Ala Brent Turner" with only 50 W input to tesla coil.
Result?Lot of unpleasant sensations and little shocks in my hand as I directed 3" arc to water pipe.
Now imagine power like 1500 W and the same situation.Me gonner I think.
Ok,people differ by their tolerance to receiving shocks but I am taking from my perspective.
And the main problem in point #4 isn't that but explanation.Small currents and skin effects when humans are conductors.Rubish.

That WOULD be useful!  Only trouble is, often enough, one man's myth is another's religion.  I can see a LOT of bandwidth being expended here, trying to reach consensus!  Fer instance, to your point #4, surely there is a coil small enough that it is thoroughly safe to touch.  But who among us can state what that threshold is?

Of course your point is largely valid and should be included among the many coiling myths.  My point is that there's a lot of wordsmithing and revising that will need to happen.
