At work today, I wrote "we have several XXs. We should consolidate on one XX."
A colleague corrected it to consolidate into.
Which is correct?
I'm English and my colleague is American, if that makes a difference. Googlefight ranks them as about equal.
UPDATE The actual XX is fairly technical and obscure so I'll use algorithm as a stand-in.
We use several algorithms for calculating the score. --several paragraphs later-- We should consolidate on a single algorithm.
The separation between the problem statement and the solution leads me to believe that skipping the preposition won't work.
