I've already pointed this out as the silly, purposeless argument it's become. (Or more become.) Even I at this point can't figure out who is advocating what or why, other than for the obvious ego reasons. You're bikeshedding at each other and wasting all the time and effort it requires, because no one else is enjoying it any more than you two are: if anything you have left your audience more confused than we began, but I see I repeat myself.

Show me you can stop doing that, and I'll happily mediate a technical version of this conversation that proceeds respectfully from the two of you each making a clear and concise statement of your design thesis, and what you see as its primary pros and cons.

For that I'll take a flat $150 for up to 4 hours. I usually bill by the 15-minute increment, but obviously we would dispense with that here, and ordinarily I would not, of course, offer such a remarkable discount. But it doesn't really take $150 worth of effort to remind someone that he should take better care to distinguish his engineering judgment and his outraged insecurity.
