It is, of course, impossible to apply a fraction of a pass to a component, That is why the requirement is to apply the nearest practicable 'time'. If the Solver program indicates 2.43 as the 'time' for the unique intensity point then you should use 2 passes for verification purposes. Bear in mind that the intensity that you are trying to confirm is not that for 2.43 but the intensity value read from the curve at 2.00 passes.
