First of all the initial question was using that suction cup thing and boiling the water. Second, there was at least one post talking about the speed to drill at. And last, your link only went to the Braxton catalog not to a video.
Seriously, you went to the curtains? I drilled 6 holes! And how many guys talked about a wet solution. Recognize the intent. Do not automatically jump to slower is better unless you can prove it. From my little experiment you can see speed variation results and if your comfortable having a rotozip in your tool box -- get one, but it's not your tool; it's the diamonds, temp, AND the speed.
Dressing th bit was only to ensure that each new speed was not effected by the last hole. Come on man! Don't you have kids in science?? You can only have 1 variable at a time.

While you are correct that my link went to the Braxton Bragg site, if you simply scroll down you would see:
"Click on the images below to view a video demo of the XCore Bit and Tile Dock accessories."
If you click on the ExCore Holesaw Video, it will appear. Excuse me for not giving such detailed instructions previously.
Where do you get that I "automatically jumped to slower is better"? The Rotozip spins at 30,000 RPM, considerably faster than other methods shown.
Dressing the bit was not about variables, it was about time consumption. If you have to dress your bit, it has to be considered part of the time it takes to drill a hole. If you have to remove or cover the lady's curtains in the home because you're making a wet mess, it has to be considered part of the time it takes to drill a hole. I'm just asking for fairness in method comparison.
