Pinlocity Rating (PR)

How hard this pattern plays, 1 (a walled house shot) to 10 (long, flat, and heavy). Tough. Computed from the sheet numbers and the load tables; no opinions involved.

PR7.7
  • Ratio 45%8.3Flatter patterns score higher. 10:1 walls score 1, dead flat scores 10.
  • Distance 25%7.339 to 41 ft is the playable band; longer and shorter both climb.
  • Outside oil 20%5.7Oil on boards 3 to 7 takes away the miss room, measured from the load tables.
  • Volume 10%10.020 to 26 mL is typical; heavier or lighter both add difficulty.
