Has anyone else noticed any extreme changes in their ability in the 2015 season?

I use the semi-quantitative, standardized, but personally relavant system of (Borg’s) Relative Perceived Exertion (RPE), with my own particular adaptation.
My training tool is the Relative Perceived Exertion (RPE) Scale, and I use cadence to chose gears to maintain my desired exertion.

RPE = 6, resting... Jim's scale = 10 to 20

RPE = 7, very, very light... Jim's scale = 20 to 30

RPE = 9, very light... Jim's scale = 30 to 40

11, fairly light...50 (my usual happy-go-lucky pace without thinking about it)

13, somewhat hard...60 (I have to focus to maintain)

15, hard...70 (I start breathing hard at about 30 seconds)

17, very hard (lactate threshold; breakpoint between hard but steady
breathing and labored with gasping)...80 (my predicted max HR)

19, very, very hard...90 to 100.
My basic training is to ride at my RPE of 50% for six miles to warm up, then cruise at an RPE of 60%, and do intervals (on hills) at 70%. I try to change gears to maintain a cadence of about 85-90 rpm on flats and rolling hills, and about 60 to 80 rpm on harder hills, to maintain my RPE. Shift up to higher gears as the cadence rises, and shift down as the RPE increases.

So I lost 26 kg (57 lbs).

And we rode two centuries (100 miles in one day) ... plus several 100 km rides, one of which we completed about 45 min faster than we did last year.
And I'm almost scampering up hills now. I attribute that to all the stair climbing I do ... and not hauling 26 km (57 lbs) around with me anymore.
Congratulatioins [MENTION=4588]Machka[/MENTION]. Weight loss is a perennial goal for me. Iwas doing well until Daylight Savings Time. To paraphrase the famous quote by Robert Oppenheimer, from the Bhagavad-Gita at the first test of the A-bomb. ”I am DST, Destroyer of Cyclists ‘Dreams.” (“I am Death, Destroyer of Worlds.”).
