Here's the stage in question, Stage 8. there were 3 banks of 3 targets, all programmed to show themselves at various intervals. distances were about 75, 178 & 300 yds. all 9 targets required 3 hits for them stay down. only one popped up at a time. the program went something like this. the first target appeared at the middle array, briefly, then a target from the short array, briefly, then one from the long array...again, very briefly. then, the 2nd target from the middle array appeared, one from the close array, then another from the far. repeated until each of the 9 had appeared to complete the initial appearance of all 9 targets. the program continued to pop up targets, in differing sequences than the original 9, at longer periods of time. plus, the program delayed popping up targets for in some cases, a long time. IAC, given the scoring was either neutralized (3 hits), not neutralized (less than 3 hits) or not hit at all, the penalties weren't substantial.
the initial sequence of appearing each target once took about 37 seconds or so. so the game plan became just shoot at the initial sequence and try to neutralize as many as you could, and at least hit the others. i got out of there in 38.12 seconds, and ate 3 un-hit targets worth 30 seconds, and 5 un-neutralized targets for another 25 seconds...ending up with a run of 93.12. gaming? not really, just taking advantage of the way the stage was scored.
