Not to that level of detail, but we can draw a few conclusions from third-party statistics and Frontier's official releases.
From my memory of the Inara ship ownership statistics - a reasonable sample, if not perfect - around their public release days:
- Python 2: slightly less than the Cobra IV
- Type-8: also less than the Cobra IV (and slightly less than the Python 2 reached)
- Mandalay: about the same as the Cobra IV (might even have been slightly higher)
- Cobra V: about half the Cobra IV
- Corsair: slightly more than the Cobra IV
... and most of that ownership level was reached in the first month of early access availability [1]
How appealing the ship itself is to the subset of players interested in buying early access ships is likely way more significant than precisely how long it was in early access for. The Cobra V was on ARX the longest and appeared to do worst for ownership; the Corsair seems to have done best despite having the shortest ARX period

it's pretty clear there that the Python 2 release was very significant compared with the background "cosmetics sales" income .. but not getting in anything worth mentioning by month 3, so keeping it open another N months likely wouldn't have made any measurable difference either.
[1] This does of course give an opportunity for the "my echo chamber can beat up your echo chamber" participants to discover how unrepresentative their friends are in all agreeing the Panther Clipper is a game-ending disappointment / the best ship ever (delete as appropriate) at a mere / excessive 1238t cargo.
