Sorry 'bout that. I meant to imply the differences between different peolple's uses and requirements and that one man's performance is another man's <whatever else>.

When my head is together, I personally define performance as something along the lines of meeting requirements effectively, efficiently, and reliably. I think I lost sight of that in my last post, and of the fact that what works at my location, elevation, humidity, temperature, altitude density, etc. may not do it for others. You're right, the enlargement may improve the air bleed's ability to do its intended function at conditions other than what I'm used to.

That's still a performance enhancement in my world (i.e. an improvement in its ability to do its job), but it's not the trade-off I painted as. I didn't think that through, but I sure didn't mean to mislead anybody or to misrepresent anybody else.
