It's good information to know how machines play after a RAM reset. Doing this on Betcoms has confirmed that it seems totally random whether the Mega Streak will give £100 or carry on for £150. There might be a reset machine on the route somewhere. Or even better than that, a flat battery!
Betcoms do have to go through quite a process after a RAM reset, and yes it seems it's very possible to run into a problem.
