TESSA47 ULTRA SLOW TAKES TO MUCH TIME TO CALCULATE FOR HAVING FUN 3-PUTTS IN 5-FT. IS ALITTLE MUCH DON'T YOU THINK ?
This thread is way out of date.
As to "calculation", there is no difference in calculation time for different speed putts. You just have to learn them.
Now putting 3 times from 5 ft is not good and does take too much time. 1 putt is much faster.
