Ann: H1 FY2022 Results Presentation, page-44

lol .... constructive discussion based on past performance when entire industry will give you disclaimer that "past performance is not reflection of future performance" but if past P/E ratio is your logic then below is the P/E ratio from 2014 (not sure where you get your data but below is based on year ending in June) with starting P/E of 16.82 in 2019... !!

so basically P/E only once reached 30 and all other years it was well below 30 and you are ignoring all other P/E only to jump to the P/E that suits your narrative ... lol.
