Absolutely agree. There is no rule for the timing of diversions; only the radar signal, as it is interpreted by the PF, is available unless the moon is out and one is clear of cloud to pick one's way through the towers.

Again, absolutely agree.
The other side of mm43's first point is, not everyone can interpret the radar's signal with equal depth of knowledge and, with understanding of what is being presented in a two-dimensional digital image essentially only of moisture returns, pick the best diversion. Experience helps a great deal but cells change very rapidly and what first appeared to be the best path through can close or can reveal another cell hidden by the first.
