Instead of lagging twice across the table. The lag could be one table length, closest to rail by the racking area.
1. This is a more natural length and comes up often in real games.
2. This eliminates the luck factor of hitting the rail, every rail reacts differently and it's a bit of a guessing game. Not to mention dead or hot spots
3. Less chance of table roll affecting the lag result. Sometimes you'll get a scratch
All of these reduce luck and makes the lag shot a better measure of speed control
