You said the same thing about a month ago. Both of the primary associations of that abbreviation/acronym are not positive to me, subjectively. That’s why I don’t call it that. Meanings matter. 
I do. I was doing it long before I ever started using subliminals. An hour is a nice, round period of time to me. There are real psychonauts who dive down/in/through/out for 3, 6, 9 hours. And that’s highly beneficial. But for now, I’m sticking with my 1. Works for me. Maybe one day I’ll feel ready for extended retreats.
Basically, I found the subliminals to be nicely synchronicitous meditation timers. A meditation timer that not only helps you know when to start and stop, as all timers do, but also doubles or triples the beneficial impact of your session? That sounds beautiful to me.
It’s funny. Sometimes, I see meditation sessions as the one formalized time during the day when you stop working so hard to lie to yourself. Like you really try to face what is here. Then the session’s done and it’s back to pretending. hahaha. Takes a lot of work to maintain these conventional, survival-based delusions, and, amazingly, that hard work is our default. And to think some people say, ‘I don’t have the discipline to meditate’. The truth is they’re too hard-working to practice. 
Anyway, that has nothing to do with your point, I just had fun writing it.
You’re speaking specifically about the length of time. (In contrast, as far as your uninterrupted streak of meditation days, I noticed that it’s way longer than mine.) It’s an interesting point about the hour. I don’t know. Works for me. Truth is, I see informal practice as a higher-level activity than formal practice. I mean integrating that style of attending and that relationship to phenomena into how we ‘move through the world’ in general.
From that vantage point, the aim is to just be meditating all the time. Just like you’re already breathing or feeling or existing all the time. Just another spontaneous expression of your nature.
Either way, thanks for reaching out @SubliminalUser .
