Haven't read all the posts but the way I solder...
Clean pipes and fittings.
Add flux to fitting (flux to only pipe if gas)
15mm heat the fitting
Once upto temp tap solder on backside of fitting so isn't visible, always work from top to bottom literally only a few mm of solder needed. You will find a bottom joint will need hardly any solder due to solder running down from top joint(people will disagree...)
22mm same process although I rotate torch back and forth to disperse heat evenly around fitting
Turbo extreme torch with mapp gas
