We have small greens (average about 360 sq metres or 3600 sq feet), with summer stress and winter water-logged wear issues. Over the years, a number of our greens have been 'donutted', where the bent turf in the middle of the greens ahs become stressed/worn/and replaced by poa. The edges had generally stayed healthy.
We used to run a 5-hole location rotation on each green, utilising the 4 corners and the centre. We now run a 4-pin rotation, using the 4 corners only. Special events have a different set of pins, that may use the middle, but we generally endeavour to keep the wear away from that part of the green (because it gets used every day by people playing across the green to the corners).
Our 4 par-3's, 4 shorter par 4's, 4 longer par 4's and 4 par-5's have a pin in each corner (the other two holes have a mix as well). The greenstaff have carte blanche within that corner where they cut the pin - it could be near the edge, or near the middle, or near an adjacent corner. The middle of the green wear issue in winter and summer seems to be overcome.
