There is a possbility that the expeditions do have the same base rate, but are indeed influenced by levels, thus we can't disregard levels until we get further evidence.

BUT we can do two seperate records in parallel, like what I'm doing with checking both base 50% and recorded base %, with one taking levels into account, and the other disregarding levels altogether. But since compilation of our results would happen at a later date when we each individually have enough data, its not something we need to worry about immediately. We may also figure out if levels matter or not by then, and only need to do one.
