center arrow and center dot on the approach (notice they line up) is 20!
Go to PBA.com, click on the details of the next tournament, then click on where they tell you what oil pattern it will be,.....they will show you a graph of the oil pattern on a lane....and at the foul line you'll see numbers.....20 15L, 15R, ...L/R standing for Left/Right
Sometimes they'll call out a different board though on the patterns....here is pattern B from PBA.com. For this example they call out board 14 which is just OUTSIDE the 3rd arrow on each side....make sense ?
