The first picture shows the AWS magnet that triggers the yellow sunflower light. The second picture shows the distant signal giving an advance warning about the stop signals. Is this of any help?
Regarding evaluation: yes you may be right. Exceeding the target speed by too much when braking gives you "reckless driving" penalty points. The same doesn't happen with acceleration. I can't remember exactly why I did it this way but there was a reason for doing so. It might be that the reason is no longer valid so I will reconsider!
