I just want to clarify that the term "ideality," when used in Foldit, does include bond lengths and angles.
Also, as Susume has brought up, fully-optimized Robetta predictions are often so entrenched with the score function that alternative Foldit models would require tons of optimization just to compete. Of course, all this extra optimization usually doesn't make a huge difference in prediction quality, and we like to encourage Foldit players to explore lots of different structures rather than optimizing just one.
For this reason, we usually "idealize" server models before providing them as starting templates in puzzles (this is also the case in Puzzle 843). This effectively undoes Robetta's optimization.
