Every statistician would certainly tell you that using stats that are not recent and validated is not useful and is regarded as junk in the scientific community. First, you base your opinion (let me state that it only IS your opinion and hence you stating what you 'think' is fact is plain and simple a myth all in its own) on what TWO people have told you and on the printout from 1993! 1993?!! Come on! How long ago was that? That would be the first thing you'd be put down on from a statistical point of view. Second, would be the data upon which that stitistic was gathered. Eleven years ago, there were no computerized methods as there are today. So, let me ask you how it is that such a data with such a high significant, numerical value can be proven valid when you have a sample size of close to 300 million people and no computational availability for you to generate such results? The Black Belt Magazine has an impact value of close to ZERO when it comes to scientific data of any sort! If you want to find real statistical data, you should be referring to mathematical journals (perhaps those with the emphasis on statistics). Hence, before you start claiming your 'facts' consider the fact that you are basically making a fool out of yourself by trying and enforce such suggestions onto the general public.
Little, don't even try to argue this. It would be a waste of your time. That is my recommendation to you.
And like Tenshinaikidoka has said numerous times, if you are looking for a martial art to help you with the defense techniques in today's world, you don't necessarily need to go to a school which would be teaching you a grappling art - BECAUSE, as a martial artist, you would learn successful methods of having your opponent not to get you into a vulnerable situation. Hence, an aikidoka would use his or her knowledge and abilities to refrain from ending up on the ground, and the attempts at doing so would render the opponent useless.
Having said that, I will tell you that grappling techniques do hold value within themselves. However, such techniques aren't the ultimate defense system in any case.
Moreover, there are quite 'modern' techniques ('modern' meaning that they were only recently introduced to the general public but in themselves have generations of use and improvement) that deal more closely with hand to hand combat in more specific situations in today's day and age. For example, the marines, and various other special ops. use 'Systema' as a training method. It was proven to be successful in SPECNAZ and is now taught to the devoted individuals willing to learn such a discipline. For more info, there is Google.
