What is the maximum timing variation allowed, given base timing of 10 degrees with +/- 3 degrees?

Explanation:
Timing tolerance means how far the timing can shift from its base value in either direction. If the base timing is 10 degrees and the tolerance is ±3 degrees, you add the positive side to get the latest allowable timing: 10 + 3 = 13 degrees. So the maximum timing variation permitted is 13 degrees. The timing could range from 7 degrees (10 − 3) to 13 degrees (10 + 3). The other numbers correspond to the lower end, the tolerance amount, and the base timing, not the maximum.
