It's not much of a confound unless you think that they would actually give us a haste bonus that's a fraction of a percent. All of the fractional haste values on gear are at least very close to their printed text so I think this is a safe assumption.
Fast Cast's contribution to recast reduction being 1/2, the minimum haste bonus (including fast cast) possible while still seeing a 1 second recast reduction would be 0.66% (6.82/1024) and the maximum would be about 1.32% (13.58/1024) before any flooring.
Since we've never seen any values so far off of the mark percentage-wise and including fast cast forces the observed haste value into this range, it's pretty safe to say that the minor bonus is 1%.
Edit: I read his test again (been a while) and given that he proved it was 12/1024, the "Minor Fastcast" bonus would have to be 0.7% (8/1024) to observe this result so I'll stick to what I said above.

A major oversight on my part was that odd total values of FC do not confer fractional recast reduction (ex: 5 FC gives 2% recast reduction, not 2.5% recast reduction). So the testing I linked to appropriately ignores the FC contribution to recast reduction (and indeed the results as a whole are not possible with non-zero FC recast reduction) if the FC from Ionis at the time was +1.
Since FC recast reduction and Haste recast reduction are distinct multiplicative factors affecting base recast (you do not add them in a common recast reduction term), FC+2 or greater would have to be accounted for (minor Fast Cast should be at least +1 so moderate Fast Cast should be at least +2) if there were even a moderate Haste effect (of which there is no evidence both in the in-game description and in actual testing once FC is considered). Not accounting for Ionis FC and assuming there is a moderate Haste effect may be a reason behind the claims of 2% gear haste.
12/1024 gear haste from Ionis may still apply though
