Oracle Bundle Patches - release timing

I have to invest much of my time (at work) into Oracle and managing of patches, merge patches, patch requests and similar things.
At this task I identified an interesting (but probably worthless) information:
It seems a Bundle Patch (for Version 12.1) is defined approximately (at least) 40 days before it's released.
At least the 12.1.0.1.171017 BP follows this rule.

I have requested a lot of one-off and merge patches on top of 12.1.0.2.171017BP over the last days. In the picture you can see 2 requests with date of 18^th and 20^th Oct. Others with Requested "Not Specified" are delivered already.
But there are some in the list with 7th and 8th of September. As my "Associated Request" ID is increasingit's shown I requested them in order (and without time machine) - all of them were requests based on Database Proactive Bundle Patch 12.1.0.2.171017 Patch 26635880 which was nit GA before 10^th of October.
So a valid conclusion is: The content of Patch 26635880 was defined before 7^th of September.
At about 7th and 8th September many merge request were raised internally - by whatever mechanism they were chosen.
Many of them were available when Patch 26635880 was available - others still pending. (Maybe they wait for more customers to request - like a kind of vote - but that's pure guessing).
Is this information of any value?
At a first sign no. As a customer still we don't know which patches will be fixed in an upcoming BundlePatch/RCU.
But if we are really demanding, we can start approx. 40 days early to force Support / Presales / Account Manager to make sure a patch for a given bug is available within next PSU/RCU.

So, if it's really urgent, don't wait until mid of January 2018 - start in early December to request your merge patches on top of  12.1.0.2.18.01.16 (or 12.2 ...)
