That was going to be my comment. The main task when braking is braking, not downshifting. You never want to give up a good braking position just to blip the throttle.
That said, I've found that I downshift late in the brake zone, when, hopefully, I've come off the brake threshold. At that time the engine rpm is lower and I don't have to jump the revs up much to make a smooth downshift.
In fact, when autocrossing, most times I don't even bother with HT, just downshift and let the clutch out. Is there a lurch? Yep. Does it make any difference? Not that I can tell.
The only time I need to do anything special is on the 2-1 downshift. Then I need to actually double-clutch, where you shift into neutral, let the clutch out, blip the throttle, then clutch in, shift to 1st, and go! Remember, HT doesn't spin up the syncros, just gets the engine rpm close to what's necessary for the lower gear.
HTH, and have a good one,Mike
