I like to choose a filter to start with that would be 1/2 to 1 grade softer than would make a good print with. I then also determine a density that is just a bit lighter.
The grade 5 blast is to taste and with normal negs I have found a 100% of main exposure is required, I will dodge areas if it is too much 5 or hit the timer twice if I want more contrast.* I call it a blast but basically just another exposure, for sanity sake I do not change the timer time once I have determined the main exposure, but count in my head and use dodging burning tools to give the right % of grade 5 and grade 0
A tip is to burn in the highlights with the grade 5, you will notice better local contrast and detail in the highlight regions if you do this.
With my workflow the 0 filter is not as important, but valuable to put soft detail in highlight regions the main filter does not reach.
Also I base the main exposure on the uppermidtone to highlight and dodge to taste. Trying to burn in detail is a pain.
