Data Analysis
02.25
| 00:00 | - Since there's so much going on while we're on the racetrack, it's often hard to objectively think back to a certain corner on a certain lap and remember what exactly it was that made you faster or slower. |
| 00:11 | This is where data logging and data analysis comes in and this can be an incredibly powerful way of finding time in our driving as well as testing different driving lines and braking points. |
| 00:21 | A lot of people think that data analysis is too complicated and too expensive to get involved in at the amateur level and there are definitely options that cost a hell of a lot of money but there are also affordable options that do the job at a level that will still allow us to learn and improve our driving. |
| 00:39 | Two systems that come to mind are the AiM Sport Solo 2 which can be purchased for under $400 USD, or if you want to include video with your logging, you can add a camera to the Solo 2 or look at a video logging system from the likes of VBOX. |
| 00:54 | Just like being behind the wheel, understanding how to view and analyse data takes time so that's why we're going to talk through the very basics of how to use data to our advantage and what we're looking for in order to improve. |
| 01:07 | Like video analysis, we absolutely recommend getting a professional driver to set a reference lap in your car if possible. |
| 01:15 | It allows you to use their trustworthy data to help fast track the learning process. |
| 01:20 | Once we have this reference lap from a pro we can overlay it with our laps and that's going to very quickly highlight areas that need improvement. |
| 01:28 | Overlaying our own data by using our best lap as a reference is still fine but there generally aren't as many obvious areas of improvement so the learning process isn't going to be as fast as it can be if you've got a reference lap that's perhaps a second a lap faster than what you've been able to achieve. |
| 01:44 | While there's a lot of techniques we can use to analyse our data, the very first place to look is the variance or lap time delta function. |
| 01:52 | This shows the cumulative gain or loss in lap time between your lap and the reference. |
| 01:57 | What we can then do is focus on one or two areas of the lap where this delta is the largest or in other words where you're losing the most time. |
| 02:07 | What often becomes noticeable during the analysis process is that the areas that need improving are often areas we may not have otherwise considered. |
| 02:16 | Sometimes it can be eveyn super simple things to change or adjust in our driving that can make a big difference. |
