I don’t quite agree with that. Inderes is independent. For me, it would be a great career achievement if a ROAST were so bitter that a company cut all ties with Inderes*. 
So far I haven’t reached that, although selling ROASTs has become harder year after year, which indicates they have developed in a good direction.
Instead, I try to identify where we “hit a wall,” meaning it’s useless to keep badgering because the company cannot, for one reason or another, disclose more. If you get stuck on one question for 10 minutes, it means missing out on a couple of other questions on average.
Personally, I don’t understand the fixation on, for example, the disclosure of AW2 sales figures; they will come when they are meant to come and will be visible at the latest as cash flow in next year’s reports, if all goes well.
