Yeah uh, uh yeah uh hum. Cool.. I don't know if dyslexia is the same for all dyslexic But in my case letters are hard to remember compared to remembering numbers. So it took me 10 months or 300 days, times, 8 hours a day to distinguish between a "F " ( bottom space on the staff ) and an "e" ( top space on the staff) At that time 2013 I was 63yrs old snd disabled with no internet access regular notation was all I was aware of . This tab stuff, using numbers would of fit the bill nicely, because it eliminates the Letters which i can't remember . Typically 8 to 12 notes sequence in a measure . I just couldn't remember the sequence even with four letters much less 8 We you can see that replacing letter with numbers is a no Brainerd and had I known about this system I could of learned much faster. But I hate to give up letter notation since I'm familiar with and comfortable with it now, .except many RU-vid instructions are in TABS
