In the Guide to the Snow load Provisions of ASCE 7-22 (O'Rourke, 2023), on page 29 there is a paragraph that alludes to Table 7.3-3 "Thermal Factor, Ct, for Heated Structures with Unventilated Roofs" needing to be replaced with Table G3-7 from the Guide.  The reasoning in the Guide is that Table 7.3-3 in ASCE 7-22 is the same as Table G3-6 in the Guide which was developed based on "the old 50-year MRI ground snow load in ASCE 7-16" and that Table G3-7 in the Guide is more appropriate to use with risk targeted ground snow loads.  I could not find a revision to ASCE 7-22 Table 7.3-3 in the Supplements 1, 2 or 3 or Errata 1 for ASCE 7-22.  Will Table 7.3-3 be modified?
