see no benefit to a higher DT at the expense of increase cycling but I maybe missing something

Me neither, every start equals wasted heat out the flue and stabilising metal work temperature, instead of real work heating the house. Long runs equal efficient use of gas.

The house didn't overheat but I can't see the point of increasing the level of cycling for a higher DT

Did anyone open doors in the house, go out and get mucky and need a shower, was it a windy day or not, have you moved the furniture about or got a new sofa. 

 

Nice idea but at my end it's just like a theoretical, like structural design model, it's there to inform, and only that.
