I'm confused. Since ARCA "now" orders hit only ECNs and ECNs are electronicly matched and then instantly executed, how could there be any "MM type reviewing of orders when hit"?

Those are interesting results. I hit MMs on SuperSoes many times per day (have done it at least 15 times already this morning) and the execution is almost without exception less than one second (no exceptions so far this morning).
I quote from the Nasdaq web site -- SuperSoes FAQ (in the quote, they are comparing the old SOES to the new SuperSoes)
quote:

end quote
So, as you can see, with a limit on execution of less than one second, the MM no longer has time to "review" and decide. For me, SS now works much like an ECN .

Perhaps you should switch to IB.
I have REDI as well on one of my backup brokers -- I'll have to try a SS execution and see if there is any difference.
