jsobo119 touched on this a bit in one of his posts (here) but I wanted to post a couple of pics anyway. For a B Leaguer like me a Ton-80 is quite rare, so when two of your darts hit the triple 20 and then the third dart bounces out of the board entirely it is quite frustrating. So the pic below may look like a ton-80 but it is really a score of 120, and then a re-thrown bounce out.
It just seems so cruel to have that coveted score escape. I don't really know if the third dart would have been in the sixty, but it would have been somewhere near it, for sure. Perhaps a single one perhaps not. I hit ton-40's often enough now that I simply do not take pictures of them anymore. So even if it had hit another single 20 I don't think I would have broken out the camera.
Here is another that I hit a while back and has just been sitting on my hard drive for a while. I wasn't quite sure what to do with it. It felt like a 180 when that third dart finally sunk into the board, and sure I aimed all three at the sixty and all three hit their target, but... It just isn't the same, thus they are not included in the official Ton-80 count. They are separate, they are false.
They are Faux Ton-80's. And I've hit two so far.
