I'd say the periscope detection would be a really tricky thing, mathematically, to code well. There's just so many factors that come into it:

Up-sun, or down-sun
Relative height of sun over the horizon
Light levels
Sea-state
U-boat movement
Duration of exposure
Distance
Frequency and duration of destroyer lookouts employment of binoculars
Zoom and field of view of same
Rolling and pitching if viewer
Weather
Expectation of seeing a U-boat periscope (after an attack high, else pretty low)

And that's just the stuff I can immediately think of!
