We used to set them at TDC, compression stoke. Had the dampener marked each 90 degrees. Follow the firing order. Two revolutions got them all.
Most everybody I know bump the starter, set the intakes when the exhaust valve starts to open. No exact point. Set the exhaust when the intake is almost closed. I check my valves each day at the races. Very seldom have to adjust one.
And, stopping at the same exact point each time would very unlikely.
Lash does not vary while checking it at different points.

Your way sets the valves consistently the same. So does my way. To each his own.
