Paradiddle Confusing Exercise

heres a dodgy exercise for the paradiddle
you basicly play paradiddle like this:
P= pressing hi-hat down wiv foot
 h)----p---
sd)rlrrlrll
 b)b-------    
 you start off doing that slowly,
then get faster and as you get faster
change sticking from snare to any other
drum/cymbal but keeping the sticking shown above
its a good warm up and hard if u play fast enough
