I just thought it over: no need for 3 stages for ID/SID abuse in DPPt, or any game really. That's how I did to build the timer I used: 6774, 25 seconds past the minute, 1st stage had 25 seconds, 2nd stage had 120 seconds (two minutes) , my delays fluctuated 6774, 6776, 6772, 6770, 6778, and I had to set the time 2 minutes before my desired time. If I needed 6774 and 35, I would have to add 10 seconds to the 1st stage. It would have been nice not to need to calculate that by hand though, and if I could to fine adjustments to the timers to eliminate a bit of the delay-fluctuation.
