Yes, it is too soon.
The numbers on the calendar page are projections based on the planned TSS values in your scheduled workouts. The UA programs don’t have planned TSS values filled in, so the projected Fitness, Fatigue, and Form will all decline as you look forward in the calendar. If you wanted, you could go in and add planned TSS values (https://uphillathlete.com/trainingpeaks-metrics-ctl-tss/). The values on the Home page are your current values. However, all of it is based on the data TP has about your past workouts. Since you’re just starting, you don’t have 42 days of chronic training load (ie Fitness) history, so the numbers are pretty meaningless.
If you look at the settings for the Performance Management Chart on your Dashboard, you can enter an estimated beginning CTL (Fitness). That’s the critical number you’re missing, since the other two are shorter term but dependant on the CTL.
You are not nearly as fatigued as your numbers make you look because you didn’t actually start with zero fitness. I mean, unless you spent several months before you started the plan lying in bed.
Also, and maybe you already know this, for any of your TSS values to be helpful, you need to have accurate threshold values in your zone settings. The program needs to know the fastest you can run for an hour, the highest heart rate you can maintain for an hour, the fastest you can swim for an hour, and the most power you can generate on a bike for an hour, depending on what activities you’re hoping to track. Heart rate is the big one for this crowd, followed by running pace. All of the TSS calculations depend on those threshold numbers, since they tell TP how close to your max you’ve been exercising at (closer to max=higher Intensity Factor). At the beginning of each new training cycle, and occasionally during them if they’re really long, it’s a good idea to retest your thresholds. And to clarify, these are NOT the aerobic thresholds (AeT) people talk about so much in this forum, they’re anaerobic thresholds (AnT)–they aren’t the paces you can maintain for many hours, they’re the average paces you can only hold for 45-60 min and then you have to slow way down or you’re keel over.
