[REBOL] Re: el(se)if constriction

Hi, P-O (or is it PeO?) Thanks for the numbers! It's really helpful to me to have this kind of comparison of approaches to a task. [rebol-bounce--rebol--com] wrote:

My habit is to rerun a benchmark test a few times (3-5) and average the results. That tends to eliminate transient events that may affect a specific timing, such as O/S flushing its buffers, REBOL doing garbage collection, and the effect of other processes running (if you're in an environment that supports multitasking). -jn-
