I would think the starter motor may stop on a valve spring wanting it to move it the opposite way?
Starting an engine and letting it run is another move that may cause less tension on the correct side.
Book procedure recommends you move past the spring tension, but here you have to find top dead center or move the crank to said position.
In a way, you can x-ray, meaning, see where your tension is all the time. Simply place the bike in gear, load the crank in such a way, you try to move the crank but do not. That means, if you look at your drive chain, you now see how tight the one side of the cam chain is, how loose the tensioner side is, by simply watching the drive chain mimic the same inside the engine. There is no need to move the crank around to some point. The point is to keep the chain tight and under pressure as you avoid the spring tension moving the chain. Besides, it's faster to do, quieter than the other 3 mentioned above.
Does it walk after 35 years of adjusting tensioners? JMO.
