Could the skill setting have a big impact on how spotting works in hull down? I've seen people suggest that Iron and elite settings can cause unrealistic issues with spotting targets?
Also the differences of spotting between the commander hatch being open compared to when he is looking through a slit could have a drastic impact (Which everyone here has most likely figured out)
Like in this video:

Although risky as hell, having the hatch open can bring some great results in hull down for the time being until its resolved....well I hope so anyway
Re-reading through and looking at the posted pictures, Steiner14 already tested it with the hatches open? anyway just posting some thoughts.
