Considerate WHAT?

A "during". 
It's not a route I frequent, ergo they'd well reached the "during" stage. 
AND since I only remember being inside 1ce, for a reason I can't remember why, so I'll need my memory refreshed as to what it was before.
BUT
B. T. W. Don't they mean "Considerate DEconstructors"?  

Must remember to use both routes to "HQ" and time/measure both to see which is best.

Moving on in time.
