Depends. Ive done well, if you are in a bigger market even if you have a crazy % market share you seem to have many more issues.
Seems they do some type of "at risk" calculation meaning if they have a group in a huge catch area that might potentially hoover up a ton of business they play hardball, small players seems to dart through cracks however unscathed.
This would basically completely shred the "bigger is better" narrative most groups try to spout. Basically the bigger you are, the more the insurance can win from directly knocking you down, the more effort and the more hardball they are willing to play. Solo guy in a smaller market goes basically unnoticed.
The "stay off the radar at all costs" narrative seems to function far better in reality. So much so that a lot of private practice consolidation I feel is almost being guided by a secret hand to the direct harm of the smaller elements being bunched up together in geographic sectors.
