The presentation is very good.

However, slide 12 is not correct in the suggestion that Return Loss is always a negative number. That is simply not the case.

The reflection magnitude in db is always a negative number, yes. Expressing it in terms of "LOSS" is negative by implication and is thereby expressed as a positive number. A reflection -20db down (negative) from the incident is a return loss of 20db (positive loss). This shouldn't be confusing to anybody, much less HP or even tomatoes.
