Going with 25-30% capacity is an enormous reduction. With all car parks and a P&R in use, plus staggered arrival and departure times, I don't the trains will be at all mobbed (assume SASTA run a 'normal' number).
The point is there is no way with a reduced crowd there will be a train every 10 minutes to and from Falmer, Railways have wasted enough time running empty trains during lock down.
