# Conditional formula to format "Personal Best"

I'm not sure if this is possible, but I'd like to conditionally format a row based on the premise that the value is greater than any previous value.

This if for recording my kids Little Athletics results. If they beat they previous time it's a PB. At the moment I can only work out conditional formatting if it's their best time, so in effect if they beat their PB every week there will only be one highlighted cell, not a highlight every time it was a PB.

Just to clarify, in the example below for 100m times:

19.2, 18.8, 19.3, 18.7, 18.0, 18.1

The second, forth and fifth values should be highlighted. It may be necessary that the first one also is as technically it's a PB. Ideally the formula would recognise this didn't beat any other time so wouldn't highlight it. I don't mind if this is highlighted though.

If you have results in A2:K2 then select that range and use this formula in conditional formatting

=ISNUMBER(A2)*(B2<=MIN(\$A2:A2))*(B2<>"")

see attached example. I generated some random times, press F9 to re-generate

Note: the above will also format cells if the time is equal to the current PB. If it must be faster then change the <= in the formula to just <, i.e.

=ISNUMBER(A2)*(B2<MIN(\$A2:A2))*(B2<>"")

That is truly awesome.

And thanks for including the spreadsheet.

I notice one small problem - in my example I allowed blanks for some races (did not compete?) but in case a PB comes after a blank that won't be formatted, so formula should change to this version to cater for that

=COUNT(\$A2:A2)*(B2<MIN(\$A2:A2))*(B2<>"")

Thanks, I'll make the change you mention as they don't do every race every week.

cheers,

Hi Barry,

I've just noticed an issue with the new formula.

If there is a gap (such as event not run during a week), then after that the first time a score is beaten it will be a PB.  Eg.

19, 18*,18.5,17.9*,blank,19,18.9*

The * show what will be highlighted.

cheers,
tony

Please ignore my last comment. The formula is correct but needs two changes for field events if anyone is interested. The final formulas (as per Barry) are:

Track events:
=COUNT(\$A2:A2)*(B2<MIN(\$A2:A2))*(B2<>"")

Field events:
=COUNT(\$A3:A3)*(B3>MAX(\$A3:A3))*(B3<>"")

You need to change the row to be the correct row. Copying and pasting the format will then work for future rows.

Thanks to and all credit to Barry for his help in developing this conditional formatting formula.
