Stay respectful on these forums.
In a grown adult, lengthening slower will create better bone and accelerate consolidation overall.
I love lengthening at 0.75mm/day at the femur because the regenerate is absolutely thicker and better quality.
Does lengthening rate actually matter in terms of 'total recovery time needed'?

So overall, in these two hypothetical patients, patient A will not necessarily recover quicker because he finished his lengthening quicker?
And thus really, there is absolutely no reason to try and lengthen quickly unless xrays show a significant risk of pre-consolidation?
Imagine spending millions of euros to lengthen just 3 cm... a bad example of willpower and commitment to yourself

Let's say we have 2 guys, patient A and patient B. Both of them want to do 6cm on femurs.
Patient A lengthens at a relatively fast rate of 1.5mm a day, and is done with his lengthening in 40 days. Patient B lengthens at a slow rate of 0.75mm a day, and is thus done in 80 days.
Does that actually mean, all things equal (i.e. assuming patient A doesn't have complications from lengthening too quickly, and patient B doesn't suffer pre-consolidation from lengthening too slowly) that patient A will have a 'full recovery' 40 days faster? I'm not sure it does.
We know that bone is growing during the lengthening period, which is why we all get checkups every few weeks to see how it's going on that end. My theory is that, regardless of the rate of lengthening, the 'total time to a full recovery' is going to be about the same with these 2 patients. True, patient A starts the consolidation phase 40 days earlier, but at the 41st day, he still only has the same bone growth as patient B. From day 41-80 (i.e. A's consolidation, B's lengthening) it's true enough A will have bone growth, but surely so will B, it's just B hasn't finished lengthening yet but when he does, he'll likely have a 40 days shorter consolidation period than A, as he grew more bone during his lengthening phase whereas A grew more during the consolidation phase.
The only way this wouldn't be true, is if bone grows faster during consolidation than during lengthening. Does anyone know if that's true or not?
Because if it's not, I really see no reason to aggressively push to try and finish lengthening as early as possible. The recovery time would be around the same overall.
The real answer is that lengthening rate is individual. Some can go fast, some can go slow. We have 0.75mm/day for tibia and 1mm/day for femur because that's what most can handle.
I did 1mm/day on my tibia for around 30 days, and after that I slowed to 0.75mm/day.
Towards the end, I couldn't even handle 0.75mm/day, I had to slow down to like 0.25mm/day, because my body was telling me to chill out.
You also risk nerve injury, if you lengthen too fast, which may be impossible or atleast very difficult to recover from.
I don't regret lengthening slow, because I don't have nerve issues related to lengthening. All my toes work, I have sensation, and I can move my legs in any which way I want.

Imagine being on this forum for 3 years and still not knowing how much ll costs.

It's not really about the raw numbers. My question is more: is total recover time going to be the same irrespective of lengthening rate assuming there are no complications in both patients. This could apply at 1mm vs 0.5mm, or 0.8mm vs 0.4mm etc.
Because if bone growth is at the same rate whether lengthening or consolidating, it would seem lengthening slower is objectively the best option (same overall recovery time, lower chance of nerve damage, and of course, an easier time during the lengthening phase itself).

It's individual again. I had another person lengthen the same as me, at around the same start time. My bones are almost fully consolidated, his not so much.
The only reason to lengthen fast is to avoid premature consolidation.
Other than that the way to go is as slow as you can because it lets your soft tissues adapt better to lengthening and be stretched easier and also the callus formation is always better and you need less time for rehabilitation.
So in the long term you gain nothing from fast lengthening but only problems. But sometimes it is the only way, especially for the first 2-3 cm and more specific in femurs, otherwise the premature.consolidation will stop you way before you reach your lengthening target.
For my personal experience the best rate for tibias are about 0,66mm per day as an average. For femurs I dom't have experience but from what I've seen with other LL'ers , 0,75-1mm are on the safe side but clearly not more than that.
A while ago I remember reading an effective strategy here. It is to lengthen the bone by segments until reaching its goal, for example there are people who have broken their femur or tibia more than once to achieve their maximum extension capacity, an intelligent and safe methodology but more expensive.
@informationispower lmao, the world of LL doesn't revolve around this site
