I wasn’t sure if it fitted here or not, but didn’t want to start a new thread 
I created a custom chart on interval.icu > fitness tabs
I then opened the custom chart tab and downloaded the chart as csv.
I asked ChatGPT if it could provide me with insights to my progress over the last 2 years and to produce a chart that shows the maximum 20, 30 and 60 minute power for each 3 month period and to include an estimated FTP, but for the FTP to never decrease only increase and to flatline where there was no increase.
It spat out this chart.
