This is the mental side though. While Caro often makes players look good because of the lack of depth on her shots. There is also a massive intangible feature that won't show up on such analysis. That is that Caro of 2013 doesn't have the aura, the reputation of Caro of 2011. I wonder how many of Caro's opponents this year have gone on to court fearing what she brings to the court, a much lower % than in 2011 that is for sure. Her opponents probably are playing better, but that is because there is no fear factor anymore. There is not a lot Caro can do to work on that apart from winning tennis matches.
Yes but look at today's match. Just blown off court by a player who believed she could win and was playing much better than her usual self for a set and a half. But that was until midway into set 2. Caro could and should definitely have done better then when she was given the chance to turn it round. This is where detailed recording stats helps afterwards.
Such analysis will also surely just cough up the obvious areas of decline, which surely her team are aware of. Obviously you would be able to break it down and see the differences in stroke production between now and 2011, but actually fixing and coming up with the solutions is a different thing altogether.
It is really staggerring how often doing a spreadsheet with actual data comes up with answers entirely different to perceived wisdom and what is thought. Just to give an example: A spreadsheet of money spent on electricity revealed a totally different answer to perceived wisdom and what is expected. That revealed leaving things on like a circuit breaker plug plugged in and switched on that is believed to be nothing actually adds up and ends up being a really big contributer to the bills.
Also, it has been posted here (and I think this includes yourself) a theory that what is coming from her and her team is contradictory - working on more aggressive especially on forehand, working on back to what got her to #1 before, working on fitness. And then there's all sorts of advice comong from commentators and analysts. So what is Caro to think deep down when it gets tough in a match.
Hard analysed data that is recorded and can be seen is vital in knowing what you are trying to do is right. Sure she may not be able to correct it. But since there is no downside - I cannot understand your objection. In no situation is she worse off for knowing that this % reason here and this % there etc is why I've not got the results I had and the recorded figures show this and back this up. It is important that what she works on, what she thinks intellectually, and what she thinks deep down are in accord and based on a sound footing.
Did Annika Sorenstam when she recorded everything in spreadsheets as to what to improve - completely unheard of back then in the very late nineties. Did she say Oh - my coaches will know what needs improving so what's the point of this? It'll just throw up what they and I know already? No and she dominated at the top as the best female golfer 1998-1999 and 2001-2005(6).
