Teams may elect to add up to 50 mL of water from an ice bath to their internal beaker immediately after
receiving the hot water for bonus points. Each team may choose their own volume.
Do any of you know how to effectively use ice water in this event to your advantage? Is 5 points extra really worth the ice water, along with more careful predictions of the final insulator beaker? Or is it useless?
Those 5 points could help if you can predict it right.I don't really know but 10 points made the difference of like 10 rankings at an invitational so the 5 points could give you an upper edge.
However since the ice water is only in the internal breaker doesn't reduce your HRF?
Since this has the possibility of being 15 points if you have a high HRF I think the ice could be a draw back.
It would reduce HRF, but that being said the difficulty is trying to determine the extent to which it would reduce the HRF score. So Long as the IWB score is greater than your loss of HRF score, it is a gain for your final score.
That being said, since the HRF score is set such that the team with the best HRF gets all 15 points, I think in order to accurately use it you'd need to have a pretty good guess at the best HRF at the competition. This introduces a bit of uncertainty, and thus risk. In addition, I'm sure prediction of the internal beaker temperature would also be more difficult, so you're also messing with that score as well.
Overall I can't imagine that the IWB ends up really being that much of a bonus. I looked at the raw scores from 2013 nationals to see which teams went for IWB. Generally, most teams that did IWB were in the top 20 or 30. However, I'm assuming these teams did well because they had spent enough time with their devices to feel confident in going for it, not that actually going for it had that much of an effect. Most teams (including the first place team) did not use IWB.
