This is interesting, because I've never found timing to be that critical. Sometimes I let my press beep away while I'm busy wrapping another mug, or finishing off a cup of tea and the print has been no different.
Also, with regard to temperatures, I know 180 is often quoted as a starting point, but how many people are actually sure that their press is in fact at the temperature stated on the display? Gary is having good results at 170 while mine works well at 180, but maybe BOTH of our presses are at the same temperature in reality. The sweet spot maybe 175 for all we know, or maybe both of our presses are reading high and we're actually both cooking at 165.
I worked for many years in injection moulding where the temperatures of the mould cavities were controlled by a bank of micro-controllers and a difference of + or - one degree could make all the difference between the components flashing or shorting. I don't think mug printing requires anything near that accuracy though, but it would be nice if these mug presses had a more exact reading of the actual temperature inside the press when cooking.
