David, you are comparing a 1/4 cup of bleach in 1 gallon of water to 1/2 cup of bleach in 40 gallons of water. I stand by my statement (bad advice) - you are free to do as you please (or you could do as the Owner's Manual recommends).
I understand the dilution ratios are different but the amount of beach used is still more than adequate. If 1/2 cup of bleach (Recommended amount for 40 gallons) sanitizes in 3 hours it will do the same in 1/2 hour. If the dilution ration was too low it would not sanitize in 1/2 hour, 3 hours or 3 days.
Your process is fine I’m just stating that with the recommended amount of bleach added to the typical RV tank there is no reason to wait hours to flush.
