E a conclusão dele:
"My machine comes on at 06:45am every morning on a WiFi timer. I am down by 07:00am & flick the GH thermometer on. I keep an eye on it as I sign on for work, make the wife a cup of tea, make the kids some drinks, watch them beat each other up etc... Once the GH hits 90°C I pull the PF prep my shot, wait for it to hit 90.5°C, quick screen flush, lock it in & go. This produces that nice flat 93°C(ish) shot, easy!
If I want to make another shot any time soon I leave the machine on & fan down as the process above explains & carry on."
Se ele vai tirar um atras do outro, ele tenta baixar a temp com o ventilador e depois tira.
