I found that plain old friction will seat them fine, if done according to the specs of the rings, and bore finish.
On the engine dyno you are right Denny.
I do understand what you mean by reverse loading.
Dad use to always slowly run them up to 70 mph and then take his foot off the gas and then let it go back to 35 mph.
He did this every time he had a new engine over and over again.
