You're referring to 'bullet shadows', this is pretty well known in the Robocode community. It can work well, (all the top bots do in 1v1) and even more so in the team context where you have more perpendicular angles to increase the shadow size, but in the heat of battle with multiple bots it is very difficult to correctly track every energy drop. The timing of detecting the energy drop is very sensitive, and if you only have one bot with radar then you'll definitely be missing exact timestamps. Even in Melee context there are only a few bots (top 3 or 4 I think) that even attempt wavesurfing, and the accuracy is far from 100%. In Neuromancer, for example, it keeps earliest and latest timestamps for energy drops to try to account for this, but this wouldn't be anything close to enough for making bullet shadows to get a high amount of coverage. In my experience here, the 20% HP bonus isn't worth the impact on your strategy and reduced timestamp accuracy of radar events. Allowing every team member be able to take on any role depending on the field layout is much more valuable.
