I thought the route sheet was good.
Where I went wrong is where it said the following:
In ALDSWORTH, TL AT TJ AND AT TJ ON B4425,
TR, SP BIBURY
I wrongly interpreted this as TL at both TJ,s and then as the next instruction TR, SP BIBURY. So 3 miles down the B4425 and the TR for Bibury was not coming I knew I had a problem, so, I came back to the TJ and only then did I notice the road sign saying BIBURY so many miles. Perhaps If I had noticed that originally I would have rechecked the instruction.
Perhaps this is something only I would do, I really did give myself a good kicking!
