I have found my strongest dip and strongest bench have little relationship... But getting a stronger CG Bench definatly helps my regular bench. But I'm only one person you will have to find out what works for you.
I still like doing dips, they seem to help my triceps grow and I just think they are fun. Wave loading could definatly work well with these
One thing I've done in the past is do sets of 3, 4, or 5 adding 5 lbs each set until I almost or sometimes hit failure. I was able to progress like this for several weeks.
