You can't force-feed muscle growth. Your body can only use X amount of nutrients to build muscle at any given time. When you exceed that amount all excess calories will either be stored (as fat or glycogen) or used for energy/heat.
In that regard your are limited by your own physiology (anabolic hormone levels and insulin sensitivity for example) in how much nutrients you can use for growth.
"Overeating" will not lead to more muscle growth if your body is already receiving all the nutrients/energy it needs to grow at an optimal rate.
Why am I saying that? Because carbs cycling (and I'm not saying it's bad I'm only giving you the clear portrait) is nothing special. It's no more or less effective than having a more constant caloric/nutrients intake provided that both gives you enough nutrients for growth.
Let's say that you are carbs cycling. Let's assume at your "moderate" day contains the right amount of nutrients and calories that you can use to fuel growth. The "high" days will NOT stimulate more muscle growth because you were already getting enough nutrients on your moderate days. In the best case scenario the "high days" will only need to an increase in glycogen storage and in the worst case it will also lead to fat gain, but no more muscle growth because your body is already building muscle at an optimal rate.
The low days will provide you with less calories/nutrients than you can use for optimal muscle growth. Will those lower days help you avoid putting on too much fat? Maybe. But they will also limit muscle growth. And since muscle repair lasts for 24-36 hours after a session it might affect the recovery/muscle building from the previous day's session too.
Correct me if I'm wrong but your mindset seems to be that you need to eat a lot to gain more muscle. BUT you don't want to get fat. That's why you want to use carbs cycling (to have both big eating and days where you control your fat gain).
It's great in theory but it doesn't work exactly like that. It WOULD work like that if your body could use all the nutrients you give it to grow.. it would work like that if eating more always meant more muscle. But it doesn't. So there is no real point in overeating a lot more than the amount of nutrients you can use.
If you were on anabolics it would work better. Why? Because the body is made more efficient to use nutrients to fuel growth.
NOW I'm not saying that you should carbs cycle. I believe that a proper application is adapting carbs intake to the amount of training volume you do on that day, to fuel the work. And those added carbs should be consumed around the workout (I believe in pre and during workout carbs). BUT you need a lot less carbs than you think to fuel a lifting workout, especially a strength/powerlifting workout since you don't really rely on glycogen for fuel during sets of 1, 2 and 3 and only a small amount for sets of 4, 5 and 6. And even during a higher volume workout you use less than you think.
If you overconsume carbs you will not stimulate more growth.
I believe that a lot of people who think they are gaining more muscle when they overconsume carbs are actually holding on more water (carbs make you retain water) and get systemic inflammation (a lot of carbs sources as pro-inflammatory).
I once wrote an article on carbs cycling many years ago, I whish I didn't because I don't believe in it anymore. I did before I learned deeper applications of nutrition. But not anymore. Except for adding pre/during workout carbs to days where the volume is higher.
