Interesting one, especially as Record supplied irons for their metal ploughs ground to (I think) 35 degrees, and recommended honing full-face. So 20 degrees does seem low.
I suppose it's a question of 'what works'. If they perform well at 20 degrees without chipping of the edge or rapid loss of sharpness - it must be OK. Though as AndyT said, there may be some differences between joinery softwoods and semi-tropical hardwoods.
Suck it and see, I suppose.
