I am a bit confused (not at all unusual), Jerry. I am assuming you mean the number of times the points open and close (i.e. one cycle = one open/close of points) so there would be 6,000 cycles per minute for an engine turning over 2,000 RPM, right? I figure a 4 cycle engine = two complete revolutions for all six cylinders to fire one time so that equals 1,000 firings per minute times six cylinders = 6,000. Or am I missing what you were saying if so you had better use small words to explain to me...

Agree 10k is decent mileage for a set of points - especially as many of us will be driving a limited number of miles so the time period will be longer than in a daily driver.
