Sorry but you are not correct. You can find the correct intervals on my website:
http://www.rugbycoach.com/fitness/test/20msrt.htm

The first table shows the interval of the first stage is 5,5 secs. This means you have to make a tape with beeps 5,5 secs apart for the first minute.

Next announce "Stage Two" on you tape and use 5,3 secs intervals for a minute.
etc.
Hope this helps,
Martin
