Dividing a summer paddock for effective grazing

[Sugar Plum]

I have access to a 3/4 acre paddock for the summer for one horse (there are other paddocks with other individual turnout horses around my one). It has electric fencing around the outside of the paddock already so am looking at ideas for splitting it to try and make the grass last. I am thinking of just splitting it in half and grazing in two weeks slots. I know if we have the horrendously dry summer we had last year that I will not have sufficient grass cover throughout, but I will supplement with hay as needed towards the end of summer / autumn. Is there anything else I should be thinking of?

Put a little track around it, moving fence line as required? Or divide into 3 or four strips and rotate grazing through each one. If you did it weekly each section would best resting the 3 other weeks.
Is there shade? Easy access to water if you divide the field?

Either do the half and half which is what i like to do, or do a track system

I love a track system where you move the inside fence in in stages to give access to more grass as you need it, it doesn't limit their movement as much as smaller paddocks can and it means when it's wet they aren't stuck in such a small area churning it up and making it take ages to recover

Longer rest periods are more beneficial so small compartments are best (for the grass, that is)

You could make a track and strip graze towards the middle. Start off one side until you get to the centre, then put the fence back and do the same with the other side.
