The problem with this question is that the sample set you define is pretty small. How many people fly acro in an RV and how many of those use a parachute? It's like asking how many people with the name Oliver were saved by seat belts on a Sunday morning driving to the airport. Even if the answer is 0 it says little about the value of seat belts.
If you look at just the RV competitors which are forced to wear one by IAC rules during practice and competition I am not aware of any accidents while doing acro. I do personally know one glider pilot who is alive because he had a parachute and you can find a couple of stories of acro pilots (even though not in RVs) which clearly survived because of a parachute.
Now the question of how realistic is it to get out the answer is it depends. There was a pretty good article in Aerobatics (IAC magazine) which showed that to successfully bail if your airplane is in a downward attitude even a prepared pilot will need around 6000feet altitude to start with. This sounds quite reasonable to me and even though I compete at 1500 feet I try out new things at 6000 feet or above to give myself a chance. I would recommend that even during flight testing in particular when doing your first spins and you don't know yet if your airplane will actually recover yet.
Also not all accidents happen in downward attitudes and in those cases people have bailed pretty low. E.g. my glider friend had a control system failure in level flight at pattern altitude and bailed successfully.
For me the decision is pretty easy. IAC tells me I have to have a parachute to play and as I have one I can as well wear it always. Why not?

p.s. My bigger issue with this whole thing is the repacking interval. My manufacturer (Strong) says annually but the FAA says 180 days. So even though there is no safety reason to repack twice a year (most of the world does annually) I am forced to do it anyway by some outdated regulation... .
