PC2021: Intermediate results, week 1

By the end of the first week, there are 817 registered participants from 67 countries (the list of countries is given below). In total, 33 solutions were submitted, out of which 6 were correct.

For this problem, I have decided to consider a solution as deserving full marks even if the answer for 2MT-strong B-fields is incorrect, as long as the formula gives a correct answer for ca 10 times weaker fields. However, those of you who have a good answer for 2MT-strong B-fields, have better chances of getting the best solution award.
