Err, well much as I hate to query a statement from a Belgrano chum like you, Strateandlevel, but I think you'll find that Item 4.5 'Approach and landing with idle power up to 2000' above the runway (single engine aeroplane only)' is an Optional item - whereas Item 5.1 'Rejected take-off (at a reasonable speed)' is a Mandatory item.
What is 'at a reasonable speed', by the way?
