Is it possible to summarize P/I ratio values according to Mack?

[m007aa]

Hello😄

Sorry for asking again, but I'm having a problem summarizing data from the Munich chain-ladder chapter.

The associated plot for this chapter (in the top right corner) uses the P/I Ratio according to Mac in comparison to the P/I ratio according to MCL. By using "summary(MCL)" only the P/I Ratios of the MCL are shown. Is there a way to also show the latest P/I ratio values according to Mack?

I would be very pleased if somebody could help me and I want to apologize again if this is a stupid question.

Many Greetings
