Checking for a value in a column of a table

We want to monitor a site that consists of a table with multiple rows and columns.  We want to check one of the columns and throw a error if any of the values is over 50.  Is this something WPM can do?

Here is an example I threw together in Excel really quick...

We would want the WPM check to fail because >= 50 would be found.  Now I was thinking about doing a basic text verification, but it would trip if the time was 1:50AM or Queue 50, etc, so that wouldn't work.
