Impossible to estimate how you’ll respond to the training plan. Someone relatively untrained can make huge jumps just by riding regularly, whereas someone already well trained has to work much harder for a smaller gain.
And thats before factoring in like sleep, diet, genetics etc.
I know its not quite the answer you are looking for, but after a couple of years at it, you start to learn what works well for you, and which types of workout generate what type of improvement for different target areas.
