First, welcome to running and the site and I hope you don't mind that I removed the link that you had to where you got your shoes. It's more of a spam guard situation and protecting advertisers who pay the Hillrunner.com bills than anything against you personally.
As for that chart and the rest of the page in general, I would argue against certain points of the page in general but the page as a whole and the chart specifically do seem to give a very safe guideline. I don't know if you can find anything better that is so specific because the problem with running is that specifics can vary greatly from person to person, which makes it impossible to come up with broad based specifics that are right for everyone. I could say go out and run 5 minute segments with 2 minute walk breaks next week, which may be just right for someone but may be too much or not enough for you depending on a long list of variables.
