Yeah definitely a generic timeline but I mean to say even the website is not accurate and there is a gap of +/-10 Days . Regarding travel, I would suggest to wait a couple of months and then travel because
1. Fares are expensive right now
2. What if they ask a new photo , you might still be able to give them one through your friends here but its too much of a work and then asking your friends to get your PR card back home would also be a pain (Ideally that is not allowed but I have seen multiple people do it in the forum. Personally I think its not worth the risk.
All this being said , if there is a family emergency please dont think twice and travel . PRTD is an option
