will still have to wait for slow coaches to play out their hand before dealer plays theirs
of course yes. But some rounds do fly by.

The fastest player to decide doesn't keep receiving cards (with the dealer waiting on each decision if to HIT again), the dealer moves onto dealing cards to the remaining players who choose to HIT/SPLIT in order of speed. Then back to he original fastest player and so on as each player requests extra cards.

ie. compared with regular tables if you had a slow player on seat 1/2 etc, they delayed the game for all the players before the dealer could move onto the other players. With the Speed tables all the other quicker players may have received ALL their cards while the time was running down for the slower player/s .....so not much waiting for slow coaches/dealer inactivity (if any of that waffle makes sense and not just repeating the obvious )
