You data can give you a LOT of high-value feedback beyond the single-session collection. One hard court session with 70% of your time above 80%HRmax is a big day of cardio stress, but your match fitness improvement doesn't rely on only ONE day; it relies on ALL OF THEM. Look at the pictures below. This is my data as an ambitious 40+ player. Data is a central part of my training, but also my coaching as well. The first is one month of data. When you can sum up your entire week of data, you can see total training duration, % time in key intensity zones, and what type of training is taking up your time. This is critical to understanding your current performance, and identifying what tweaks you need to make to your training plan to improve! The second is the year-to-date data. 8 months of data, presented in total training duration and intensity zones per month. You can see the month-over-month the variation in time and intensity, which can help you understand your past training quality and volumes and, more importantly, adjust your training plan moving forward to maximize your progress. It can also give you total # of sessions, average duration, and even the overall time spent in each intensity zone (e.g, 60 HOURS of time above 80%HRmax). And while all of this can be a bit overwhelming if you try and ingest it all at once, that doesn't mean it's too complicated or not valuable. You wouldn't eat all 3 meals and snacks and drink all the water you need for the day ALL AT ONCE before 6am...but you do need it all to maximize your day ;) Like this post if you like this stuff!
