Scope limitation: the underlying spreadsheet checks bending stress using a nominated section modulus. It does not calculate connection/fastener/anchor capacity. Vertical member length, horizontal arm length and bracket spacing are retained as project inputs but do not change the current bending-stress result.

This mirrors the spreadsheet comparison table for 1–10 brackets. With the default 50% conservative maximum-load-share assumption, increasing beyond two brackets does not reduce the conservative single-bracket design load below 50% of total mass.
