VTEC allows you to run two cam profiles. The low-RPM profile is pretty wimpy and is designed for good fuel economy and civilized idling. The motor would run out of breath shortly after where the VTEC crossover was supposed to be if VTEC did not kick in. The high-RPM cam is lumpy and designed to make a lot of power. It also is too aggressive to actually idle. So, the VTEC system switches over from low to high at or around the point where the power curves intersect for the low- and high-RPM cam profiles (at least theoretically speaking). As far as your original question is concerned, it doesn't make much sense at all.

So basically its a compromise of how much I can tune it towards high rpm while still being able to idle well enough.
