In regards to real world applicable shooting skill which can be mastered with less than weekly practice, this shows the basis of a good start.
Gunsight and the other Jeff Cooper-ish sight picture shooting stuff doesn't transition well from competition to real world. Very very few people you will ever meet will claim to having been able to see their sights in a shootout or simunitions fight. It contradicts instincts, and you likely won't be able to overcome the adrenalin rush screaming at you to point shoot. If you like sight picture shooting up close and can devote weekly intensive practice to it, go for it. Otherwise planning to "focus on your front sight" is suicidally stupid.
