you think we must training fully army to hit 1 outside TH?

The point of this algorithm is to try and use only a few archers for sniping TH and to deploy more troops in case that fails. Perhaps it can be done in 3 or more troop waves, not necessarily full army from the 2nd wave, perhaps it could have an UI option to adjust the number of troop waves. At lower leagues you can use just a few archers to snipe, but after crystal II, it's really hard to find an outside TH without tons of traps and mortars, etc around it.
