FIRST ADULT - Processing Times (+ when/how are the original documents returned?)

Hey all, Just thought to let you know that for my 1st adult application the processing time from application to passport delivery has been less than 1 month (and not 7 weeks as originally advised by HO). Does anyone know when/how the original documents sent are being returned? Actual times: Passport delivered by TNT 11 November 2021 Passport printed and sent 3:19pm on 8 November 2021 Application approved 9:46am on 7 November 2021 Documents received 11:50am on 18 October 2021 Application received 12:56pm on 13 October 2021 Identity details received 12:56pm on 13 October 2021 Email sent to person confirming your identity 12:37pm on 13 October 2021 Ask someone to confirm your identity 12:27pm on 13 October 2021 Application submitted 12:27pm on 13 October 2021 ***NOTES: 1) TNT deliver 8am-8pm - you need to be in to sign for delivery and they do not advise est. eta whatsoever. 2) Original documents are to be delivered separately. Do not know when or how. If anyone knows, please share! Thanks!
