# Mapp the differences of pockets

Hello i wanna know if i play a 1,5 to 3 wheel speed, and i measure the time with 1 second, and i dont wanna to know specific speed, only difference in pockets.And the rotor makes within 3 and 4 spins before the ball falls.( i know that is not the same but aprox )And i wanna make for me a clock mapp for differences in pockets.I know that at faster rotor speeds if i was looking at 12 i have to look maybe at 9, and for less speed maybe at 3 .But now if i wanna make a clock mapp for me in distances of 0 to 4 pockets with the time of 1 second and with rotors speed 1,5 to 3 , can you help me,please ?

Sory, but I surrender :o

I would recommend, begin with a rotorspeed not under 2.2 Sec. up to 4.0 Sec.
Depends where u live .
I don’t like speeds less than 2.7 Sec.

not sure i get your drift - but if you look at clocking pattern - then you could read observation point by kelly at vls forum …
then you can create your own clocking pattern and adjust with different rotor speeds / adjust and change observation point

Sorry lucky, I am not up to date or have forgotten , where is it ?

,then you could read observation point by kelly at vls forum …

Observation point by Kelly at VLS Forum « on: July 18, 2009, 12:56:17 AM »

There seems to be a lot of confusion on the observation point on different rotor speeds. I`ll try and clarify.

First of all, a traditional VBèr always predict at a specific ball revoloution measured from behind. On a spin with 15 ball revoloutions he will predict around 10 or 11 nd on a spin with 18 ball revs. he will predict at around 13 or 14. How he knows how far he has come in the spin is another explanation.
Because he always predict at a specific time away from when the ball drops, this time is always roughly the same. If we say he predicts 4 revoloutions out we can as an average and for the easyness of explanation say that there are ~ 10 secs. until the ball drops.

So we know that the ball travels for 10 sec. when we make our prediction.

The differeence in the observation point is because the rotor travels more or less pockets with different speeds, and the second factor is the scatter which also differs with different speeds.

So imagine we have a 4.0 sec rotor speed and a ball running time of 10 sec. from prediction. We have an average scatter of 10 pockets. The rotor will travel 10/4 = 2.5 Revoloution. Which is 2.5 X 37 pockets = 92.5 pockets we then add the 10 pockets scatter and have 92.5 + 10 = 102.5 pockets.

From looking at some 4.0 secs. spins we know this point at this wheel with X tilt is, say 1 o`clock.

Then we suddenly gets a 3.0 sec rotor speed. We know from analysis on this wheel and this ball type, the scatter is slightly longer say 13 pockets. The rotor will turn 10/3 = 3.33 X 37 = 123 pockets + 13 pockets scatter = 136 pockets. That is actually only 136-102.5 = 33.5 pockets away from our 4.0 sec rotor speed. Which gives us a clock key point at 12 o`clock (or 2 o`clock if the wheel turns the other direction, the key has simply shifted 3.5 pockets from 1 o`clock)

Of course we have done these calculations before we start the play and has memorized the key pattern in the head.

3.0 = 1 o`clock 3.1 = ~ 2 o`clock (moves 4 pocket from 1 o`clock) 3.2 = ~ 3 o`clock (moves 8 pocket from 1 o`clock) ..... ..... 4.0 = ~ 12 0`clock

It gets a lot more precise if you draw a wheel map and plot the calculations point directley in so you get a specific clocking key. And don`t forget the scatter change. Its not good enough to just adjust observation point in regards of rotor travel lenght, you must add the specific pocket scatter, no matter what the difference is. In the example we added 13 pockets for the 3.0 sec speed and 10 pockets for the slower 4.0 speed.

Hope this clarifys.

PS: This key asumes 10 sec. running time. Personally I predict around 9.1 - 9.4 secs. out, so my calculation will use the most frequent measure on a specific wheel. With different ball types and different wheel types, 4 ball revoloutions isn`t always the same. A Garnite track with a Delrine ball, doesn`t give the same running time as a Teflon ball on a old Mahogany track. So make sure you know exactly for how long your ball will run from when you predict. Usually its only a small amount of pockets in change in the new key, in other cases you get a small chock when you compare your new clocking key on a brand new Huxley to the one you used on the 4 year old Joost wheel you played last week. It could mean the life and death of your daily bankroll.

Hi my friend many thanks, must read now, my wife wants to go to bed ,
in Germany is midnight now.
