Not sure I follow. I looked back at my last easy ride (I don't often ride in groups just me and the hills) and it was Z2 40% Z3 40% and Z4 20%.
My previous ride I was pushing hard and doing intervals on the hills and it was Z2 28% Z3 49% and Z 4 22%.
Those are pretty typical for easy / hard days on the same loop.
