Sounds pretty close to me.
At 1030 Spl and 56% Crit, I'm seeing around a ~21 Spl = 1% Crit.

Now to figure out a simplistic method for reuse...

Slippery

People overvalue reuse. First off, with the right gear Bolt of Ice is capped and Fission is getting damn close. The next thing is that it takes a fair amount to make a real impact. It is also the human variable, for it to matter it has to be casting the instant it comes up, which odds are it doesn't because you are mid casting something else.

When you don't have enough of it, more is invaluable.

When you've got enough, you can't give it away.

Before I got the 5% from my (warlock) mythical, and 5% from the TSO troub AA, I needed more. Now I don't need anymore. Well, depending on all the other buffs like TC. And jcap (large chunk!) still gives a very noticable improvement to dps... not to mention RoA and DR, though those give cast haste and recovery also of course...

While it's non-linear, you can certainly apply some kind of average value to it. Not sure the best way, but I think somewhere around 1-2 reuse = 1 crit is about right, just off the cuff.

Troubs don't get 5% reuse from an AA........

Have I got the amount wrong?

Aria now adds 10% base damage and 5% reuse for all spells, doesn't it?

Edit: Thinking about it - it's from their mythical, not TSO AAs, right?

Pinski

No. That'd be from their offhand weapon, Marrow's Song
