Four graphs of weight by lumens (Base: 96 HPS-only YOR records)
Here are four graphs of weight (grams per sq. ft.) plotted by decreasingly precise values for HPS lumens (96 ungrouped records; 29 groupings; 20 groupings; 10 groupings):
For the next graph, using 29 groups of HPS lumens, here are the ranges of actual HPS lumens w/in each group, and a count of the number of reports in each group:
