Permanent stat bonuses (Belts / Headbands / Stones) and Mythic points

[General Chaos]

What effect do effectively permanent stat bonuses on maximum Mythic points?

It seems obvious that the maximum Mythic points would be increased, which is fair because you can only get up to +3 extra points that way.

But then there's the Dual Focus, you could quickly (and easily) end up with +5 maximum Mythic points at high level, for the cost of a single mythic feat and another belt/headband, where other abilities or feats only provide +1 or +2.

I think that it's somewhat fair, because it's also likely that you'll burn through mythic points a lot faster at higher levels, especially when fighting against foes of appropriate challenge. Things like Amazing Initiative and Force of Will are probably going to be used very often, if not every round - not to mention casters that might use extra mythic points to power their spells.
