There is still no Classic putting in Mobile but I would assume this formula could be easily applied simply by understanding that the Standard putting grid seems to travel at half the speed of the Classic(Flash). So if you count the dot speed in Standard, then double it and apply to this formula it should be very close.
I agree. Hope the classic dot speed option becomes available for the mobile version ASAP. It would save the time on the green dramatically.
Mobile only player here. I use this formula. Just count the dot speed from the middle to the next grid line, divide the green speed by that number. If your green speed is 12 and you counted 4 from the reset of the dots to the next grid line, your multiplier is 3.
You also have to account for the fact that many breaks don’t all run at the same speed and you have to kind of look at the line and see where it is faster or slower and compensate.
Been there, done that. To me, it was too inconsistent to be called a formula or a method.
I'm not saying you're wrong or Danny's method is fake. It might just work well for you but not for me because apparently, based on the conversations I had with friends (all top-notch players), we all get different dot speed depending on the performance of each individual's computer (device). The better your computer is, the faster the dot speed.
The multiplier (divisor) is, therefore, very subjective.
