I am not that good at math! I just drew it up in Mastercam and measured it there.
3 thousandths. Trig says 2.25 x sqrt(3) = 3.897 (using ratios for the sides of the 30-60-90 triangle formed by the 1, 4 & 10 in bbb's pic above).
pj <- but who's counting?
Kinda sorta, but not from the same cue ball position. The 1/2 ball hit is the point of discussion, not the same spot on the object ball.so you guys are saying you aim for the same spot on the object ball, whether it is on the spot or 4 inches below the spot.
if i take it right that is exactly what you are saying. or am i missing something here.
Within .001" - Mastercam's not too shabby.I am not that good at math! I just drew it up in Mastercam and measured it there.![]()
Not the same OB contact point, the same visual overlap from a different CB position.so you guys are saying you aim for the same spot on the object ball, whether it is on the spot or 4 inches below the spot.

I don’t completely understand your post but a half ball hit on an object ballthen on one of the shots you are not using the optimal cue ball position.
and on any shot there is an exact spot to hit for the shot to have the best chance of going. i guess if you can move the cueball so that the exact half ball is easier to hit than that works. but you still are not aiming at an exact spot on the object ball.
HEY! YOU JUST INVENTED (another) AIMING SYSTEM!The cue ball placement changes
its amazing if you pay attention
how often you aiming a half ball hit ( or close) to pocket the ball
half ball hits (same aim spots ). Occur very frequently when playing

For comparison, here's an easy way to see where the CB goes for a half ball spot shot. Looks like your diagram shows about the right amount of adjustment from there.Another quick drawing. 50x100 rectangle, ball where the 10 would be if racked, ghost ball aimed very slightly high to hit the wider part of the pocket due to the reduced angle of entry. 30 degree line (half ball hit) bisects the headstring 3.92 " from the rail. Throw, spin, table and ball conditions can vary, so this is only a reference, obviously.

yeah, thats the point, it's easier to aim at the edge than a spot on the object ball periphery, if you know the edge is correct. In this case we do. If the ball were on the spot I would place the cue ball on the head string and almost a full diamond towards the center string, a half ball to a full ball towards the nearest rail.then on one of the shots you are not using the optimal cue ball position.

But for those who know the object ball doesn't have an edge -- and I think you know who I mean -- that can't work. The rest of us just go on in our happy ignorance and aim to the edge. This technique has been used for about 200 years.... means aiming at the edge of the object ...
LMAO- The prefect user name to make posts like this.Well, if you want to be exact.......
Patrick is still off by 2 thousandths.

I think my opponent is going to call a foul. Maybe even unsportsmanlike conduct.If you want to see if a shot is a half-ball shot and you don't have a protractor or PJ's drawing program, here is how you can test on the table using just the balls. This diagram shows how to find the half-ball spot for the cue ball on a spot shot. The 1 is on the spot. Place the ghost ball against the 1 ball pointed to the pocket or slightly towards the left side of the pocket if you want to compensate for the throw. Freeze the 2 and 3 as shown. All four balls in the mini-diamond need to be touching. The line from the 3 ball to the ghost ball -- the points of the diamond -- points back towards where you have to place the cue ball for a half-ball shot.
