I don't doubt it has helped you - it often does help people... Initially. It will simplify the first pull, which can translate into quick progress for a while. But invariably what happens is that athletes reach the point at which the weights they're handling exceed what can be managed with that type of start/1st pull positioning and they suddenly plateau.
So by all means, do what works for you. Just keep in mind when you reach that point, you may have to relearn the start and first pull.
