Borrow Later vs. Regrouping

I have created a new website at Borrow Later that discusses a new way of subtracting vs. the standard regrouping (borrowing) method.

I'd appreciate a mathematical critique of the system and any comments would be greatly appreciated.

It's a completely free site and it only takes about ten minutes to understand the method.

Thanks!
