So SMN did the zap queen and inferno. On the first one the Queen and inferno died and he 3 stared.
On his second the Queen lived by a sliver and 1 star.
Not sure there is a way to avoid the variance of it but looks like it can be quite powerful.

These are the updated patterns. Looks like you need to aim a bit left on the first, then dead center on 2, 3, 4 then a little left on 5 to get the most hits to the queen.
Looks like you could get
4, 5, 5, 5, 4 hits on target. That would be 2185 hp from a max which is basically exactly what you need to take down the two key items with margin to miss one hit perhaps on the first shot meaning you could just take dead aim and still get what you need.
For a TH9 4,5,5,5 *85 = 1615 which is AQ39 so it seeeeems like you should be able to do this easily at TH9 with an AA. Likewise at TH10 could use just 4 zaps to do an AA/AQ kill and save a spell.
