Narrative:
I was working a parallel monitor position. A B737 was the lead aircraft; a B767 the trailing aircraft. The B737 slowed more than expected at the FAF. I instructed the B767 to slow to final approach speed; and he did. Two point five miles was required; and it went down to 2.36 at the time the B737 was over the approach end. The rate of compression had reduced; and I made a conscience decision to allow the B767 to continue the approach. Spacing was sufficient for the tower; and there was no danger of a go-around due to long roll out of the lead aircraft with current conditions. There was no reduction in safety; and no danger to the users. Local control 1 had made the transfer control point (tcp) 1 mile; but a few airplanes later went to 3 miles; which would have made the operation legal. I honestly don't know; with the new confusing quality control order; if we still have an approach end; or if this is simply a mandatory occurrence report (mor) now.
