Hi Sam,
Yes it is OK to do Small universe at your own speed. Some of us who had the audio tape version re-recorded it at a slower speed. I'm not sure about how you would do it on a CD but no doubt Someone? with expertise will tell you how.
That said if you follow the current version you will find that you have to the count of 4 to inhale and another count of 4 to exhale which gives 8 seconds. This is actually a quite slow rate of breathing and is recommended for people with Blood Pressure problems to get their levels back to normal. Breathing at less than 10 breaths per minute is helpful for lots of health problems and Master Lin in his SU only uses 7.5 breaths a minute!Hope this helps clarify things,
Good luck
