I hear you but I do not think the average risk-averse Joe cares whether it is 1 day or 3.5 days - once they are in the "this trade has to profit 100% of the time" mindset, I do not see anything over one hour working for them.
If you have a human sleeping schedule, 3.5 days often work out as four so I would prefer x.75 or x.25 day timeframe in case there is a change but that is cosmetics.
