Xan makes an interesting point about Simpsdarts in that the scoring is kind of confusing. For example I have played in at least 3-4 tours this season were we have scored this as bull:

But actually the signs are connected to the rung below them. If you look at the bottom of the map there is no sign for the very bottom rung, which would support Xan's theory:
BUT if you look at the top the 10 sign is still on a rung instead of standing on its own into the air.

Maybe I am just overthinking it now, or maybe someone should edit the map a bit to make it more clear?

I presume we have not been scoring it incorrectly all season... Worm sits on top of the sign it scores for, right? Like I said I have played in tours with Hurz scoring it this way... I did not even think about it until Xan brought it up today.
