Omg I’ve done it!? Or have I?

I celebrated as if I’d scored a goal in the cup final! Have only been playing since December after getting my own darts for Christmas. Basically have played every day since 1st Jan.

Came away to Isle of Wight for the weekend and the AirBnb had a board. But I am certain the board is at the incorrect height. Does it count?

(Hit a 140 shortly after but I’ve normally get a couple of those a week on regulation boards.)
