PC2021: Intermediate results, week 2

By the end of the second week, there are 853 registered participants from 68 countries (the list of countries is given below). In total, 49 solutions were submitted, out of which 8 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.
