HOW TO ANSWER
Please note the MAX PULL UPS performed WHEN you were climbing the grades that you note.
For example:
In 2017 you performed 10 pull ups at your maximum but climbed 13b.
But then in 2018 you did 9 max pull ups but climbed 14a.
Answers: 9 pull ups, 14a OR 10 pull ups, 13b
You may answer twice if you wish to include both results.
