There is a lengthy thread on the adjustments made to workouts since the move to Systm. [Why have workouts been made easier in the new Systm app?](https://wahoox.forum.wahoofitness.com/t/why-have-workouts-been-made-easier-in-the-new-systm-app/11488) Thin Air is noted by some (including me) as potentially needing the ftp numbers bumped up by around 10 - 11% to bring it back close to the original Suf version. @Coach.Neal.H offered a pretty comprehensive explanation on why many of the workouts had been adjusted, this included an assessment of users actually completing sessions. I suspect that the old TA would have had a very high failure rate as sustained efforts are probably the most challenging type of workout for many. I regard sustained efforts as being a real strength, and my best 20min effort still remains a TA session from around 10 months ago. Having said that, I recall I still had to pause a couple of times to catch my breath before continuing. Next time I do TA I expect I will bump up my ftp numbers, but certainly not by 10% - more likely 5% --- _[View the full topic](https://wahoox.forum.wahoofitness.com/t/thin-air-is-a-completely-different-activity-now/15961)._
