Of course this is a lot easier than rotating the crank several times, but I haven't heard of anyone doing it this way before. Has anyone done it this way, and is it ok?

You can do it that way but it's much less accurate when you're working with a cam with lots of overlap...like yours.
For experiment, I've done it both ways and there were about .002-.003" difference. The EVO method is much more accurate...
Remember that Steve Christ wrote that book ages ago....it serves an ok purpose for factory style lower performance builds, but just doesn't serve a purpose for more modern hipo engines.
