According to App State's blog post from Day 3, they indicate that they traveled 210 miles, with roughly 40% SOC left.

Today has finally been proof that our car is capable of much more than we’ve been getting out of it so far. We have not had any major issues on any fronts. It’s now 2 o’clock and we have already traveled 210 miles but here’s the best part: we still have ~40% state of charge left, and the sun was generous enough to show itself today. Not only have we already broken our record for distance traveled on a single charge, we aren’t even close to being out of batteries. Team Sunergy is tearing through Wyoming -- we’re now only a few miles away from Casper, WY where the next checkpoint awaits. Rough estimates gauge that we could go up to 300 miles in conditions like these, even more with better sun & roads.

210 miles / total = (100% - 40%)

therefore, we have that

total = 210 miles / 60%
      = 350 miles

Let's use the 300 mile estimate that they give to be conservative.

For reference, our best day had us travel almost 390 km, which is a total of 242 miles.

350 miles - 242 miles = 108 miles

Where are the other 108 miles going?

The best output we ever got from our array was -7.2 A.
