True, I found the difference in Access pretty odd too.  Go figure.  I
definitely have to move my Integer 'bad practice' to strictly VB.  I was
just assuming that it would be applicable in Access too...but I never tested
it in Access, since VBA is a subset of VB.  I tend to do my more math
intense stuff in VB though....

That's what I get for assuming....

Are you aware that this is an Access list?  ;-)

Looks like the VB compiler has some tricks to optimize 32-bit integers.
What's interesting is that the complete opposite is true when this is done
in Access.

Either way, I don't think it will cause anyone on the list to refactor their
code to squeeze out a few extra ticks of performance.

I ran it in debug in VB, and got only a slight variation....Longs being
slightly faster.  However, your code compiled produced:

3405 ticks (integer)
2193 ticks (Long)

(Repeated runs get close to the same)...
