On My RTI (Request To Information) on this older Series CBSL replied
Information on issues after 1987.01.01 or 1996.02.01 are not available with both the CBSL and the printer.

From the rough proportionality of the Replacement note serial number with the cumulative Total Number of regular Notes of that denomination printed in Thousands we can estimate that the number of replacement notes used is probably about 0.1-0.2% or on average notes per thousand of about 1 for lower and 2 for higher denominations. i.e. Replacements used is 1 to 2 times the column Issue K

The serial of Z/4 675K for 580M Rs100
