They won't tell you anything you wont already know from the current players relative sizes, etc.
Combined, digiweb and novara grow are in position 2, and their growth rate means Blacknight will re-overtake them in about 6 months or less (as they signup more customers).
Register365 growth rate ensures it stays out in front (some months growing more than 5 times more than the next guys).
The rest of the market is smaller providers, who will slowly but surely get 'swallowed' up by the larger firms / external firms over the next year or so.
