It was raised by a few players at our Virtual Club sessions that the pairing for each event didn't feel random in that they played many of the same players each week despite there being only 9 rounds and 38 pairs. The turnout has been pretty similar each week with similar pairs, so is there an algorithm going on here or is it random and this is just one of those unlikely events?

If it's a stratified tournament, as the ACBL virtual club games are, it tries to distribute the strats evenly. This may result in encountering the same pairs because of the relationship between the strats.

The case here was just an EBU Virtual Club session with no stratification, but it looks like the players involved only had one repeated pair a few games in a row (which is not uncommon) and did particularly badly against them :)
