In reply to jasonpather:
I made a 'stubby' moonboard in my garage. I shortened the kick board and made the handhold rows 18cm, rather than 20cm and missed one row off.
With regards to the training, I still use the moon app but take the grades with a pinch of salt and if you're imaginative you can still make hard problems work and get what you want out of it.
Hope that helps!
