The data I've seen from various sources appears to indicate that skill level has no effect on yields. There are people reporting a massive drop in demimateria yields with higher skill, and others reporting massive gains with higher skill. Looking over all of the data I've seen, and using my own experiences to back them up, I strongly believe that your skill has no bearing on what you get.

Also, with a 60% chance to desynth Ifrit Blades, I successfully desynthed two of them. The second gave me 3x Demimateria of the Inferno.

The data I've seen suggests that the drop rate for Demimateria is close to 10%. However, the data (which is admittedly a very small sample size) also suggests that items that can give multiple demimateria can also give fewer demimateria with an equal chance. So, theoretically, if Ifrit Blades can drop 3x Demimateria of the Inferno, they can also drop 2x Inferno and 1x Inferno, all with 10% drop rates, for an expected yield of 0.9 demimateria per desynth. But, I don't really have the evidence to back this up. I need more data...

But, if this is right (which it likely isn't), it would make Artisan/Forager tools better than the hats, since for Artisan's, it's 5x the cost for 9x the chance of mastercraft demimateria (since they can give up to 3x at once), and for Forager's, it's 2x the cost for 9x the chance of mastercraft demimateria. Need moar data!
