I've been told when I was a WP that the auto/computer assessment can take up to 24 hours.The auto assessment takes 30-60 seconds.
I believe @Kangol is saying that manual assessment after the bot has declined the request is a P1-only benefit.
I don't know whether the bot has declined my previous WP requests. The rep lodged the request with the bot, the request wasn't approved on the spot, and was then sent for manual assessment. But maybe the bot is capable of more than just approve/decline responses, and when a request is borderline, the bot sends it for manual assessment instead of declining? We will never know unless someone with hands-on experience of how the system operates can chime in.
In any case, it's clear from all the responses that there was some level of manual assessment for WP requests prior to the pandemic. As far as I'm aware, that hasn't been reinstated at this time. If the bot does not say yes, the answer is no.
Whilst most yes results occur almost instantly, there are some that don't (I have had this before - a delayed yes that I only found out 24 hours later, told this was a system delay, not a manual intervention).
The value of the manual review is when you hit the end of the road and you are declined. It sounds like some WPs here have had an outright rejection, then been told that it would be sent for an Oliver Twist type "please sir, can I have some more?" manual review.
I've had this happen to me when as a WP (outright no, this is the end of the road for you) and specifically told a WP cannot request further assessment and only a P1 can.
Could not be any clearer.
Maybe something has changed, I wouldn't ever want to find out though
