Another tip to add: When I did it, I was refreshing the page when I was about to lose so I didn't lose my winning streak and could get another bonus from itnext match.
I also was quitting on the match at first turn if I didn't get +1 Action on first turn or %30 dmg bonus, that allowed me to fight again without losing the win streak and get one of the two bonuses at the start of a match.
These two bonuses are the most helpful ones when you fight against computer.
And beware of the insane mech, it can double shutdown and can still hit you even if they are still overheated after the double shutdown. The drone gets disabled for that turn though. (dunno if they fixed it now, but it was this way when I was fighting them)
And Aeacus, I have remembered it wrong, yeah you are right.
