Everyone needs to get stronger of course, but unless you are super-strong and can do multiple one-armers without technique (chapeau), training for a 1 rep one-armer is just a waste of time that could be better spent on 1) increase general strength and 2) practice skills with higher transfer to climbing.
Strength is usually best trained in the 60-90% of 1rm range. If one-armers are in this range, more power to you.
