Yes and no.

Yes changes to the VE table may change the calculated GM.DYNCYLAIRPID's value.

It won't have the "jump to the next cell" type effect that you suggest because of the interpolation performed by the PCM.

The PCM calculates a weighted average of the looked up value with its surrounding cells, based on how far the lookup indexes (indices?) are from the row/column labels.

See this thread for an explanation of interpolation:

It shows the VE table in the example, but the same logic can be applied to looking up values in any table - including spark tables.
