If you think we disagree, then I was obviously not clear enough. With 7 VSE guests, the amount of resources each could get at any time will be (far) less than 400% (all 4 CPUs). If more than 4 of them working, each gets even less than one CPU worth of cycles. So one virtual CPU will do. The drawback is that with just one virtual CPU you can not get more than 100% of a CPU, not even when all the others are idle. That may or may not be a true concern. While you're right that wall clock time is what counts, performance measurements help you understand the difference between two experiments and allow you to improve performance other than through trial and error.
