Agree that for race-specific prep it’s important to digest the intensity and keep riding (probably even higher than L2). But I’m not in that phase yet. At the moment my focus is L5 + L2 and later on I’m going to mix things up and throw in more race-like sessions, threshold under fatigue etc.
I guess I’m taking from this related discussion that I’ll be conservative in terms of the intensity of the L2 I add in the end and rather stay at the lower end of the spectrum (-> same benefits, less fatigue).
