Is perma-PA possible for exemping down to Synapse TF on an Ill/Rad?

I'm trying to rebuild my Ill/Rad to be as exemplar-capable as possible down to level 20, but I can't quite close the gap to account for the casting time on Phantom Army.

The build I'm currently tweaking is below.

I'm aware of the cost for some of these sets. They are within my means, but if there's a more efficient slotting, by all means, fire away.

Also, how badly does enhancement scaling crimp this plan? For example, would the 2 level 50 recharge IOs in Hasten get reduced to approximately half of their effectiveness, and slip out of perma-hasten?

http://paragonwiki.com/wiki/Exemplar...n_Enhancements

Any level 50 IO is going to have it's effectiveness cut down to about 55% of its effectiveness at level 50. So, if you had 3 IOs in PA, you need 6 for the same effectiveness.

So, look at what you have in PA: you have 102% Recharge before ED and a 6.25% global IO Set Recharge bonus. At level 20, the 102% becomes 56.1%. Add in the bonus and PA is at 62.35% Recharge (plus the other global recharges which I'm ignoring for the moment). Now, if you put in 6 Recharge IOs, you get 137.7% after the exemplar cut which is then 100.7% after ED. This is much higher than going for an IO Set.

Since the lowest level LotG:+Rech is 25 and Synapse exemplars you to 20, you're more than 3 levels under the IO... so they would be useless.

With 100.7%, you need another 199.3% (it's 300% total recharge for Perma-PA, right?) in Global recharge.

Since the exemplar cut is cutting into Hasten and Accelerate Metabolism, too, making them no longer Perma... I don't think you'll be able to do it.

If I had known I would be using Math for real world types a sh...stuff...like figuring out how to get Perma PA at level 20, I would have applied myself more in school.

Damnit General Math!
