Since I asked in this in the wrong place:
I saw this by accident. I don't post in training anymore.
I do not separate into off season and on season.
Sometimes I do power and strength each workout over a 3 - 5 week cycle, each workout also containing hypertrophy work.
Sometimes I use a 3 - 5 cycle which rolls week to week from speed sets (power) through heavy stuff (strength), each workout also contains hypertrophy work.
My DL workouts are usually a heavy(ish) single to double followed by speed triples. Else it's the singles only thing working up to a few heavy singles over a few weeks.
Then, I will do sets of 10 which might be touch and go, might be with pauses.
Sometimes touch and go for sets of 10 just feels like good work. I don't think that they will ultimately help my pulling. Triceps, lats, traps, erectors, etc. get a pump and I'm all "hey everybody, there's a bodybuilder over here!" Of course I lift alone so who "everybody" is, I don't know.
I'm not smart enough to answer your question well. But...I "think" all deadlifts for the sake of the deadlift event should be from a dead stop.
Deadlifts used for some other purpose (hypertrophy, cardio, "bar's still on the floor I might as well look busy," other) can be done in some other fashion such, for example, as touch and go.
I feel that I do power and strength each workout or in short order over a few weeks, often adding hypertrophy work. I think one can do power, strength and hypertrophy simultaneously or in short order and not need to split it into seasons. I think all deadlifts for the sake of the deadlift should be paused. I think one can do touch and go deadlifts if one is using that movement for something other than strength or power relative to competition.
