All I ever asked for - was that I be told scientific truth - while I was still able to read the 20/40 line - and get myself back to 20/20. But scientific truth is "tricky", the OD will tell you. I know I made my choice, when I was at 20/40. https://www.youtube.com/watch?v=1pO51N9Ahek
Yes - Todd was successful.
Because he did not, "hold back" on the wearing of a plus lens.
Because he resolved to PASS the only real requirement (Pass the 20/40 line - or better).
But people who demand 20/10 (that they always get from a strong minus lens) will most certainly become permanently myopic.
It is all a matter of your educated choice.
