Well, it's about 330 with RR engines, but anyway, relevant to the topic. I saw the first unsuccessful start attempt lasted more than 3 min. After that according starter limitations there should be a cooling period of 30 min. Never mind - FADEC allowed the second attempt without any message.
This is the first reason I use stopwatch - to control starter limitation. The second - to keep the habit for manual start.
Another related note: there is no SOP to start timing on takeoff. We start it to control the takeoff thrust time limit. Not sure the aircraft would give any message in case of exceedance.
Another case, when limitations are not guarded by the aircraft. You can enter quite a wild ZFW and ZFCG, well above limitations with no warning message and get Gross Wieght again well above and again - no warning.
It's not perfect...
