I tested INNER in the range from 10 to 40. The following was the only
suspect effect that I saw here (Pentium II, 400 MHz, 256 MB RAM,
Windows 98, Eu 2.4).
Using the 'ex.exe' interpreter (in a DOS box):
- INNER = 27: 1.10
- INNER = 28: 1.70

The other steps in the tested range result in smaller time differences.
I didn't get such an effect at all when using the 'exw.exe' interpreter,
and I wasn't able to produce a dramatic effect such as yours.
