There are many many variables when it comes to training. For example:
The type of training split you use.
The exact exercises you perform.
The rep range you train within.
The total volume you perform.
What, if any, assistance movements you perform.
All of these things matter some. None of them matter at all in the absence of progressive overload. Bottom line: if you are squatting 315 x 5 today, and this time next year you are squatting 315 x 5, you will not have grown. Period. End of story.
It is irrelevant how much per-session volume you performed, whether you squatted high bar or low bar, how much rest you took between sets, how many times per week you squatted, or what assistance movements you did or did not do. None of these things matter in the absence of progressive overload.
An alternate case is also true. If you squat 315 x 5 today, and this time next year you squat 365 x 5 or 405 x 5, you will have grown.
