IF the search results were skewed to favour BB/staff, then Margot, Michael and staff would sell more domains than anyone else, hands down. We know that is not the case, there are many of us that are outselling them, even you on occasions.
DNBolt actually broke down a month here:
https://dnbolt.com/blog/brandbucket-june-2016-sales-review/
So lets look at the percentage of each portfolio that sold that month
(personal names intentionally removed):
16 names sold from a portfolio of 5528 = 0.29%
4 names sold from a portfolio of 447 = 0.89%
3 names sold from a portfolio of 1006 = 0.3%
3 names sold from a portfolio of 234 = 1.28%
2 names sold from a portfolio of 561 = 0.36%
2 names sold from a portfolio of 781 = 0.26%
2 names sold from a portfolio of 109 = 1.83%
2 names sold from a portfolio of 98 = 2.04%
2 names sold from a portfolio of 192 = 1.04%
2 names sold from a portfolio of 2386 = 0.08%
So of the top 10 that month, Michael was 7th and Margot was 10th. You also sold 2 names that month
and so did at least 3 others with small portfolios at that time. That means Michael was actually 10th and Margot was 13th and you were above them both.
