This UOA is for a 2017 Audi TTS with a stage 1 tune, used both street and track. The same oil was left in for consecutive UOA's:
1K miles and 2 track days, and an additional 1K miles and 3 more track days.
The onle notable change in the oil was the increasing TAN, which measured 3.7 on the VOA.
The increasing Silicon was traced to the air inlet hose not properly seated to the turbo inlet pipe. Easily remedied, one good reason for doing UOA's.
The oil has been changed, and it looks like a schedule of 5 track days or 3,000 miles is fairly conservative going forward.
