Should I stop doing RC?

If you saw my other thread, 'Induction Technique Immunity?' you'll see that my brain is somehow capable of showing the right result despite my rather detailed Reality check (Each doing 2 time, every hour)
I did Reality Checks in my dream, almost every time, but it result are always correct.
Should I stop and find other ways?

Try pinching your nose and trying to breath in.
This will work because your not realy pinching your nose, just your dream nose.

I haven't read your other thread, but some reality checks tend to work less frequently than others. The physical ones such as the finger-through-palm, or finger-counting RCs have a tendency to be less successful than the nose-plug RC, because it's very difficult to emulate the sensation of blocked airways. This may be because in real life, you're still breathing normally. I'd highly recommend you try out the nose-plug if you haven't yet, and as for the others, really expect a dream-like outcome when you do them. Truly expect for your finger to go through your palm, for instance, visualizing it as well as you can.

I agree with the nose-plug thing. In my experience it's 99.9% foolproof, and I always use it as the bare minimum.

What concerns me is your approach to reality checks. They aren't about the frequency/quantity at which they occur - they are about the quality; they exist solely to make you become aware of your state of reality. Someone who did no reality checks a day but paid attention to everything they experienced would stand a much better chance than someone who did 100 reality checks a day.

I rarely reality check because I focus on awareness (the only thing which makes you lucid). It's times where I'm really not sure if I'm awake or not when I'll perform a reality check (and also before I go to sleep and when I wake up for the sake of distinguishing whether I've been subject to a false awakening).
