I have always tried to be between 9 seconds and 25 seconds if at all possible
This gives me a opportunity to count, remember times and as well dodge. This is a repeatable timeline.
Longer times do not always mean easier dodging, as dodging is a % of the main time and therefore you need enough time to set your tools but you still have to hit each area to a specific % . Does that make sense?
I sometimes dodge the whole main exposure , just giving different areas a defined % . Having a long time does not make this aspect of dodging any easier.
