Jur93n,
For myself, the past moment can be observed in 'this' moment, it can be run forwards - backwards - stopped - run fast - run slow. All with my attention in the Now - seeing and hearing the world around and with my attention on the past scene.
There are times, that I slip away in to the Past scene and lose the Now, that is when I know I am still on #3 as it is these moments 'the bank' has taken over control - that's fine, as soon as I realise I dropped out of PT, I can realign myself and start again.
Interestingly (or serendipitously), this landed in my universe today from another source:
This very interesting conglomeration of questions, of course, are designed to strike straight home to the lowest level of aberration on the analytical plane. And I had an awful time dictating these questions. I had a formula set up and I was just reading off this formula and so on, and all of a sudden I'd go out of present time and then I'd come back up to present time and I'd dictate a few more questions I'd figure out, then I'd find myself . . . I all of a sudden discovered that I had been sitting at the desk for five minutes doing nothing, see—I'd get back up to present time and go on with my work.

For me then the Intensity, relates to how much it pulls me from PT - I am not aware of any past scenes that cause me any discomfort anymore, pretty much run all of that stuff out with other practices.
