A lot of folks put too much into other folks line out numbers. It is only a guide, which helps you know if someone is in the upper column, middle or near the bottom.
Perfect example: 2 fisherman in the same boat. Each using their own rods/reels pulling Jet 40's. One fellows jet tag bottom in 40 fow at 105 ft braided line out, the other 135 ft of another brand of braid ( same brand/model reels)to tag bottom. This was running 4 rods/2 each.
The amount of line backing, line type/size and amount of main line type/size all changes the calibration equation/line out numbers. Some folks calibrate their reels, some only to 100 ft. Me, I don't care as long as I start with all my reels spooled exactly the same. I know they are all very close, till someone looses a lot of line
Once I know at what water column area/level the fish prefer the bait, I can start working on giving them plenty of it
If the bait's profile, bill length and angle are real close to each other. They should/will dive very close to the same depth. Given all the other variables.
Just more stuff/experience that has changed the way I think about fishin compared to when I was starting out.
