I'm still here, or here again, on our shiny new board.
There are 2 sides to what you set out.
First there is the pre-working/post-17 UK education/training time where you provided evidence to DRV. That would be added to your German record (while also, potentially, forming part of your UK record, though university time in the UK shows only as a gap in your record). It might also add Entgeltpunkte to your German record, not just Wartezeit, depending on the nature of the education/training. If you have a Rentenauskunft it should now show an "innerstaatlich Berechnung" based on your German record and you should see those study periods in there. It should also have a "zwischenstaatliche Berechnung", that would show the aggregation of your UK and German records - see below.
Then there is the aggregation of your UK and German records. This is used in the zwischenstaatliche Berechnung and aims to create a contiguous record from when your UK record started when you turned 16, until you reach German pension age. The UK works on weeks (even though only full years count for UK pension purposes) and Germany works on months (you need 60 months, 420 months, or 540 months for the 3 different pension options) and if there is a contribution on at least 1 day of a month, that month counts. So, given how the UK year is April to April and can have 52, or 53 weeks, the German system is Jan to December with months, and some of your UK education may be shown in both records, you should see a table setting out how the two systems are aggregated to create that contiguous record and also showing which overlaps have been disregarded. You are correct in saying that this aggregated total will be what is used to get you to 420 or 540 months absent contributing for that long in Germany.
When you come to claim your pension (or ask for a Rentenauskunft) you should see 2 calculations over oodles of pages. They are the innerstaatliche Berechnung, which is the amount of pension you would be due looking only at your German record (including those UK periods of education/training that were added). This is the same calculation they would do for a German resident who had never worked abroad and in EU regulatory terms is called the "Independent Benefit".
Then they do a zwischenstaatlich Berechnung, which assumes all contribution periods were in Germany (using that contiguous aggregated record) to arrive at a "theoretical amount" of pension. This is apportioned based on your actual German record. In EU terms, this is the "Pro-rata Benefit".
You pension (or pension forecast) is the higher of the two and because of how the German system/rules work, it is possible that the Pro-rata benefit is a higher amount than the Independent benefit, i.e. your UK years add Entgeltpunkte as well as Wartezeit.
As I mentioned, you should see this in your Rentenauskunft, which they provide periodically, unless you request one in between.
When you claim your pension at 63 or later, using your aggregated years, you will not see the detailed innerstaatlich Berechnung if you do not meet the 60, 420 or 540 month requirement without aggregation, as the answer would be zero, so they save at least half a forest of paper!
If you are having trouble sleeping, there are some really good training products on the DRV website, aimed at their staff.
