Summary

Description
English: Diagram showing margin for error in covering single-pin spare in ten-pin bowling.
4.25 + 2.375 + 2.75 = 9.375" range of success
FYI: board width = 41.5" lane width divided by 39 boards = 1.0641" per board
  • Diagram purposely ignores possibility of hitting the 10-pin if ball is just falling into gutter because its trajectory after leaving the lane surface is speculative. It is extremely unlikely that the ball will take a very small slice of the 10-pin during its fall into the gutter, since the ball will be approaching the pin within about 3° of "head on" and would either (1) take a fairly big slice of the pin (almost as much as the "right" ball pictured above), or (2) fall into the gutter missing the pin altogether.

If picturing together, I recommend using same image height for all.

The margin for error in converting same-row splits is about 1.25 inches (3.2 cm).
Margin for error for converting a single-pin spare: balls thrown outside a range of about 13.25 inches (33.7 cm) will miss.
Because the 10-pin is located close to the gutter, the range of success is smaller, about 9.375 inches (23.81 cm).
