I'm compiling a set of results for performance tests that I am doing against a web site.

Let me give an example of what I'm doing.

Cells A3:A300 are urls
Cells B3:B300 is run1 avg. response times in ms
Cells C3:C300 is run2 avg. response times in ms
Cells D3:D300 is run3... and so on

I would like to apply conditional formatting to highlight when run2 is slower than run1 on a specific url, i.e C27 is slower than B27, and I would like this highlighted so I can make further investigation.

Thanks,

Ant
