Presumably, with 4❤ and 5♠, after Stayman we still bid 2❤first? With a weak hand and 4❤, 4♠, 4♦and 1♣, we can bid Stayman & pass whatever partner bids?
Thank you for your questions. With 4H and 5S we wouldn't be balanced enough to open 1NT, so would open the bidding 1S. With that 4:4:4:1 holding and weakness, Stayman is useful as we can pass any response partner makes to get to a reasonable suit fit.

With that 20-point hand and the 5-card Diamond suit you should bid 6NT . Even without the SQ 6NT should make if Clubs break 3-2.
There isn't a hand with 20 points in this video - maybe a different one?
