Can anyone explain why there is sometimes a silent aural block in the N=2 level on stage 4?

I find it confusing. Thanks

I’ve been doing this for a couple of days now.
Not sure if it is a direct result of doing these exercises, but I noticed that my attention span at work was significantly better yesterday.

I have stayed with Section 2 for a bit, even though I hit the target of n=6 relatively quickly. Mainly because I’m enjoying it and I want to see if I can become more consistent at n=6 before I move on.
I can win at Level 4 every time and Level 5 seems to be the place where I win some and lose some. Level 6 it tends to falls apart.

Continuing to struggle with N 3. N 2 is really easy. I feel like I’m making progress, because N3 beginning to feel different. I focus primarily on the letters. The visualization seems even harder.
