This has nothing to do with him finding it confusing, is has to do with cornering though - Have you tried the "fastest lap calculator"? And in that case, what do you think of it? Thinking of buying it, i just dont know if its really worth it.
Not sure exactly what that is but I assume it is something similar to the 'best theoretical lap' option that is a part of my QStarz laptimer software.
It has its uses, but also needs to be taken with a grain of salt.
For instance, my software will pick apart my laps by the entire track broken down into little segments then add up the fastest segment times to give you a 'theoretical best lap'. Meaning if you did everything right, that is your optimal lap time. It is good for a goal but it is inherently flawed as your fastest times in a particular section are highly dependent upon your entry and exit lines...which are affected by your earlier section trajectories. Still, it makes for some interesting discussion.
Here is the thing about lines, and this goes WELL beyond the intended scope of this writing. For the vast majority of turns, there is no magical one right line. (the one line to hold them and on the asphalt, bind them!)
One of my favorite questions to get (sarcasm) when instructing is for riders to ask me to show them my
line with the assumption that I am fast, so my line must be the fastest line, right? Now, I understand why people ask me this and so I just chuckle and offer the following explanation:
Lines are determined by the rider skill, handling characteristics, and speed of the motorcycle. As all 3 of those things can vary quite a bit you will find that what works for someone else may not work for you. Hell, I even have different lines depending on which bike I am riding. For example: my line through turn 9 at my local track is completely different on a 70hp SV650 than it is on my 127hp ZX6R.
So, to me, those 'fastest lap calculators' make for some interesting fun and can certainly offer some insight, but overall there is no way for something like that to be 100% accurate. Hope this helps!
