I would say the conclusion is a bit of an understatement - with 5 snapshots the graphs show performance degradation of 500% at best, and 5000% at worst...

Put another way, unless your SQL Server is under about 2% load or less, then putting in 5 snapshots would have the distinct possibility that your server would then be under 100% load.

Of course, that's an over-simplification, and the tests aren't very specific about the bandwidth of disk IO etc etc - but even so, those graphs are distinctly scary.
