Yeah could be, if the reduced recovery doesn’t affect the quality of the session for you.
If the plan is expecting a 90 min sweet spot session but you don’t have the time, select a 60 min one instead. You’re still working the systems expected, sure there’s a hit on TSS but that’s just a description of the work you did in the time.
If I’m doing a time trial I’ll look to swap out the threshold session, or most threshold-like session in the week.
There have been times where I’ve tried swapping 3-5h endurance rides for higher intensity rides but it doesn’t always workout well, you’re better splitting the ride in two and doing the second half when you can, if at all.
In my opinion the vast majority of the benefit is doing a workout at all. Getting every precise element perfect is like…marginal gains if any.
