TSS goes down as well as up?


Maybe i’m going crazy but when i am watching my TSS i see it occasionally decrease, is this some bug in the calculation or intentional side effect?

I tend to especially notice it when coming off a high intentsity session, so for example, warming down, when presumably my TSS acculumation rate would be vastly reduced… not presumably not negative!

I’ve noticed this as well.
What I presume is, when you are currently riding at a power under the rides current NP, there is a rounding ‘issue’
The TSS might get to 61.6 TSS, then because you are riding for longer at a lower intensity than the NP, it drops to 61.4 TSS, then you’ve added volume so it’ll pop back up again.
