What's a good On Axis %?

Spread the love


If 44% is random, what do most of the good rollers log for this % ?

I’m sitting around 49% in my most recent 500 rolls with a SRR of 1:7.12

Well, might as well give it all to you:
Toss Count 477

Sevens to Rolls Ratio (SRR) 7.12

Box Number to Sevens Ration(BSR) 5.03

Both Die On Axis 233 48.85%

Primary-Face hits 60 12.58%

Single-Pitch hits 125 26.21%

Double-Pitch hits 48 10.06%

One-Die Off Axis L: 92 41.72%
R: 107
T: 199
Both Die Off Axis 45 9.43%

My understanding, the best strive for 50% or more. The key is keeping it over time. Looks like your well on your way.

DannyP,

Be patient. You don’t have enough rolls to be statistically significant. You need a minimum of 3600 but 5000 or 10,000 would be even better. Expect change. Keep practicing.

Good rolling

Have you gotten to 5.000 yet?
Good Rolling.

Cutting Edge Craps has all the information about on-axis throws.

Is not 67% random.

There is 6 numbers on each dice4 of those being on axis 2 not 67%.

Rember as the great no field five put it during a videio tune up you can influence the dice in both ways negative and positive.

A good practice session for me is right around 75 to 80 percent on axis

I think random with both dice on Axis is 44.44% (16 of 36)

Thank you oh so much.

So do i keep trasck of when one dice is off or when both dice are off?

I look at it like with fifty throws there is 100 chances that one of the dice or both could be off axis.

On a good night i will get some where around twenty hits that there is a one or six that is out of one hundreed.
So that oulwd bring my on axis down into the 60 something percent range, correct?

With each throw there are 16 ways (out of 36) for exactly one die to be off axis, 4 ways (out of 36) for both dice to be off axis and 16 ways (out of 36) for both dice to be on axis. Thus there are 20 ways (out of 36) for exactly one die or both dice to be off axis.

In 50 throws there are 1,000 ways for exactly one die or both dice to be off axis and 800 ways for both dice to be on axis. Since there are 36 possible combinations on each throw of two dice, there are 1,800 possible results in 50 throws.

If you are able to reduce your throws to where you only have 20 hits that have a one and/or a six out of one hundred throws, that means the other 80 hits are on axis for an 80% on axis ratio with both dice. That is a FANTASTIC number of on axis throws. As Pointman and I said above, random is only 44.44% with both dice on axis. If you can do 80% that is phenomenal ❗ ❗ ❗

What is the on axis percentage for this run of throws/

2-2 2-2 2-3 2-6 2-3 2-6 2-2 2-4 2-3 6-4 6-4 6-2 2-6 2-2 4-6 4-6 2-6 6-6 2-4 2-3

72.5% on axis ?

Posted by: Skinny on March 23, 2013, 7:00 am

50% on axis. Every roll with at least one 6 or 1 is an off axis roll. You have ten of them. Every roll with a 6 or 1 is an on axis roll. You have ten of them as we’ll.

10 on axis rolls out of twenty rolls is 50%.

A roll is on axis if both dice are on axis (ie. no 1 or 6 on either die).

If you roll a 4-6 it is not a 50% on axis roll because one die (4) is on axis and one die (6) is off axis. A 4-6 is 100% off axis and 0% on axis.

You count both die as a single roll not two separate rolls of two dice.

Does this make it clearer?

Your example has 11 sixes and 29 non sixes. 29 divided by 40 is the 72.5% you came up with. But that is not the correct way to count on axis rolls. You do not count individual dice separately. You count the two dice as a single roll. Your example has 20 rolls (of two dice) not 40 rolls (of individual dice).

So the 6-4 is counted as one off axis roll, the 6-6 is one off axis roll, the 2-3 is one on axis roll and the 2-2 is one on axis roll. So while there were 8 individual dice in my sentence, there were only 4 rolls of the dice.
