I would like to ask a question regarding P1.T3 Page 39. In the example for strengthening on May, basis is ($0,10), then there are two scenarios discussed in columns, weakening and strengthening scenario. Under Basis Weakening Scenario, Basis is stated as ($0,05) and Basis Strengthening scenario, it is $0,05. What I understood from notes and my search in internet is, if basis is getting more positive then it is a strengthening. But here the basis on May was ($0,10), and in both two scenarios Basis is getting more positive;

($0,10) < ($0,05) & $0,05

, so basically in both scenarios it is strengthening compared to May Basis. But in notes scenario with ($0,05) basis is stated as basis weakening, is there a mistake here or did I understand the topic wrong ?
