Is the method repeatable mate?

In my view, provided you don't abuse It and be systematic with both the method and timing between each SE, I don't see why not.

True, suppose anywhere can be done more than once.

It should work more than once for most people. Personally i have done it twice, but with a time span of about two weeks. They are not the biggest company, so it should be fairly easy
