@derek-m - I agree, see above, the efficiency loss caused by raising the LWT matters, but I still think empirical data is the best way to determine ho...

@derek-m - no problem, here they are (posted publicly in the interests of open data etc etc; the relevant column heads should be self explanatory eg a...
I agree, the setback is used to effect an on/off switch (and have said as much more than once!). Limiting the drop in IAT as you suggest is certainly ...
