Hill rep's

i've started doing hill rep's on a 1 mile hill start's of flat then progressly get steep then the last 1000 yards kicks up to 20%,

i've been rideing the first one steady, second rep standing up, third rep slow at the bottom then fast at the top, fourth fast at the bottom slow at the top, am i going about this the right way,

would like any ideal's on how to improve, main goal is to ride 1 mile hill's fast

i ride a similar type hill. i ride it six times, seated, highest possible cadence i can manage. would also love to hear what the experienced folk have to say about hill repeats .

Sorry to everyone i should have ask this queston on the training forums.
