That is what I'm thinking too. I think the water and fuel are falling out of suspension due to the very cool intercooler air charge. The range the combustion in the engine likes is around 60*F to 120*F air temp. So next year I want to add even more water when I start using pump 87 octane. I'll have pump 87 on the main fuel rail and my GEM/water mix in the secondary fuel rail.
