hashrate dependence on mask order

[drsnooker]

Thanks Chick3nman! It's still not quite clear from that faq.
Is what you are saying, in the case of 
312161N114993?u?u?u?u?u?u?u (slow) 312161N114993 is the word that runs in the base loop, while the ?u runs in the mod loop, 
while in case of:
?u?u?u?u?u?u?u312161N114993 (fast) there is no base loop and everything runs in the mod loop?

edit:
I did try this on mode 22000 and see no real difference in hashrate there.
