Note that you can determine such timings yourself using the 50g's TEVAL command. For example, put << 1. 1000. START 1.5 DROP NEXT >> on the stack and execute TEVAL to time it. Now insert either CEIL or 1. + IP between the 1.5 and the DROP, and use TEVAL to time each. Divide the times by 1000 to see the difference. I keep << -40 CF MEM DROP 0.5 WAIT TEVAL -40 SF >> assigned to a key for accurate timings.

Why do you have MEM in the programme? TEVAL does garbage collection.
What's the point of 0.5 WAIT?
