That seems fine, but it would bug the heck out of me.

I always thought a taco was when a wheel was bent to the point of no return, such as so much bending that the rim cracks so from that definition any taco is bad.

Yea, you might not want to do more than 1 or two revolutions of the nipple when truing your own wheels unless you really want to mess around with spoke tension. It is better, I believe, to adjust one or two more spokes if it means you only have to turn each nipple a eighth or a quarter of a turn.

Also, remember that you are just doing lateral true and while fixing that, you almost in all likelihood messed around with the radial true, i.e. your wheel is no longer a perfect circle though I do believe most people on here would place lateral true in greater importance that radial true.
