smaller sprark plug gap for Mag.... why?

[Peter]

I ve been thinking about this...
everybody says a mag delivers a hotter spark than whatever... 
Now if that would be the case, why is there the need to decrease the spark plug gap when using a mag?
I thought when the energy is higher, you can increase the plug gap???
Is it to overcome the low energy the mag has when starting ( like low rpm's)

That would make sense and I can't see any other reason, run a test set at say .030" and see how she fires up, I ended up running  025" on my Turbo Rallycross motors, it was never "clean" at .035" gaps.
