Good catch, Dave. I agree entirely with your caution about using data points that are recent and truly max efforts. This is one reason that I prefer the MMP protocol of riding at a constant power to exhaustion. I get a good data point (assuming I am relatively fresh) every time. BTW, Freddy, I think your big jump in your 20MMP demonstrates that doing L4s at the low end of the L4 level (~90%FTP) will result in the desired adaptation. If I have read your recent posts correctly, you have been doing your 20min efforts at about 275W. I actually don't think you need to increase your intensity to reach your year-end goal. I would favor increasing volume at 275W (e.g., adding a 3rd 20min effort or doing 2x30) over increasing intensity.
