Just to answer questions above: I had been doing 10-12hrs prior to vacation, left with CTL around 80 and TSB -9 and came back CTL 68 and TSB +35. I thought I'd be a bit sluggish for a couple of rides but now a couple of weeks back my HR/RPE aligns with power set 7% lower compared to what I was doing before I left (I use 2 power meters trainer and pedals and they're consistent). I'm surprised at how much lower I have to be at the moment. I wasn't all that keen on taking a week off right before starting build, hopefully can claw back a bit in the next few weeks
