Tester type	Replacement scenarios	Supplementation scenarios
Never testers	N/Aa	1 test per year 2 tests per year
Opportunistic-only testers	25% replacement 50% replacement	1 additional test per year 2 additional tests per year
Risk-based testers	25% replacement 50% replacement	10% additional probability of testing after risk event 20% additional probability
Regular testers	25% replacement 50% replacement	1 additional test per year at random time Decrease the intertest interval by adding 1 test per year
