If so then doesn't this cause a problem, since the Jitter could be as much as 25% and this value is added on top of the network jitter.
Jitter is always *subtracted.* I believe the text is clear on this.
The receiving end neither knows nor cares; it calculates the Detection Time based on the parameters and times out. All that the jitter does is raise the frequency of received packets by an average of 12.5%, which provides more robustness rather than less.
