Changing Erection levels while jelqing

Im currently on my second week of the newbie routine as i am starting again as i did a month in october but couldnt continue but i did manage to gain 0.1 inches.

I dont know if this is a problem at all but when i am jelqing my erection level never stays exactly the same across the time that i jelq which is 10 minutes.For the first 2-4 minutes i am around 80-90 percent erect and my squeeze is firm but very comfortable and the head of always seem to be very shiny at this point.Also when jelqing at this particular level my penis does seem to throb when i get close to the head as it fills with blood as if im kegeling but i am not.

Between 4-6 mins my dick may get softer at around 50-70 percent erection which means my holds must be a bit stronger as the penis is softer and not as much blood is coming in.After this period my penis is back to 70+ erection level just as it was in the beginning and

and so i was wondering if these changes made any negative differences at all to gains.

Also my PIs are all positive probably because im 20 years old and i usually get morning wood every day anyway but my penis is still prone to shrinkage throughout the day so that hasnt changed but i hoped to have a heavier hanging penis the longer i follow the routine.

Any thoughts and advice from anyone would be very helpful for my PE Journey in the short and long term.

Thanks
