I was about to make another post related to this. But many thanks for the same. I was thinking about the ratio of 1:4. If there are 92000 POB's then there is 368000 VYB's that must have gone out from this account. But your comment answers couple of the questions.
So just for my understanding, it is probably the collection of all the #pob in the single account @x-1pob-4vyb rather than different accounts @x-1pob-3vyb or @x-1pob-2vyb. Is that so ?
