I live in California and our premium gas is typically 91 octane.
The next exit down the 101 from my house has a station that sells 100 octane unleaded.
Would it be of any benefit to run that? It's nearly 2 x the cost.

No, not really. If you can get E-free fuel so much the better but the GRiSO has a very nice, modern, combustion chamber and will burn just about any old lizard piss. Certainly a higher octane rating will probably make it smoother and less prone to detonation under heavy load but it won't give you any real performance advantage.

Normally run Chevron or Union 76 premium on the 07 but the other day they had a screwed up touch screen so had to use mid grade. I swear it ran better on that stuff.

The old Olympic stations out here used to have a purple 103 octane that made the garage smell sooo good.

If you can, run the highest octane ethanol free fuel available. FYI, ethanol bumps the octane rating up too.

I THINK the 100 is ethanol free.  We typically get a summer blend of 10%

The local used bike forums are full of folks that left their old fuel in long enough to glue everything together. I just cleaned the rock hard residue out of the jets on my brother in laws small bore single trail bike.

This "magic " gas is destroying garden mowers, outboards, gen sets and anything else that doesn't get run once a week. Now they want to bump it up to 15% , corn lobby is strong in USA .

I refuel with ethanol free premium (93 octane) fuel at my business. I can get it from my fuel distributor where I buy off-road diesel for my equipment. When traveling, it has become almost impossible to find alcohol free gasoline. With my GRiSO, I can definitely feel a difference in fuels, and for winter storage, I make sure I have topped off the tank with the "good stuff".

Well crap. They no longer have a 100 octane pump.
They will sell you 5 gallon cans of it.
