Spot on MR8. That's why the whole thing stinks. Evryone above you has the same option to pull out if the situation on the bus changes. All your calculations and considerations will be a jab in the air. It sounds great not having to commit, especially at EK, but this leaves the whole exercise to be as accurate as the RTA's road planning........
I just let it flow and it will still turn out the other way.
