This seems to work quite nicely - thanks. I'm not yet sure how it works,
but I will figure it out !!

I've plotted the original data alongside the smoothed data for both your
suggestions & they are both very good. The 2nd option might be better for
me as it does not require the row number of the last entry (your $A$20), and
my data is updated regularly.

Thanks again

Hi,

This can only ever be an approximation, but the following should give you
something to work with.
Assuming your truncated data is in A1:A20, enter the following in B1 and
drag down

=A1+(COUNTIF($A$1:A1,A1)-1)/COUNTIF($A$1:$A$20,A1)

or use

=A1+(COUNTIF($A$1:A1,A1)-1)/COUNTIF($A$1:A1,A1)

for a slightly different set of numbers
