It is entirely possible that in some windows all block producer slots will be randomly assigned to the same producer. While this is statistically unlikely, it is not unreasonable to presume that a long sequence of blocks could be assigned to collusive peers.

Could you be a bit more precise about what you mean by 'unlikely'? For example, within IPCC documents the term unlikely is defined as having a probability of zero to 33%. Is that similar to what you had in mind when writing this section? Thanks.
