Chinny sitting out in the current 75+ meters out...the rod tip is not pointed at your feet...it is pointed away from you 75+ meters out...
So...for example...you hold the rod up with the fish loading the rod...we'll assume that the rod tip is held 2 meters up...the fish is 75 meters out...which gives a sine angle of 1.5 degrees...which means the rod tip is not pointed at your feet...as depicted in the video.
Even if you are standing on a rock that is 10 feet above the water...now giving the rod tip a vertical distance of 5 meters above the waterline, you are still looking at a 3.8 degree angle.
The max load, in your given case, is distributed across the entire arc of the rod with the rod tip pointed outward. The rod would NEVER bend over in a teardrop shape as depicted. It would be a semicircle at best. The pressure would NEVER concentrate into a tiny little arc at the wide end of that teardrop shape.
Again, video is unrealistic...unless you try to highstick a fish as you go to land it...but we all know what a headshake can do to a rod when you highstick it...and it will not be the slow and consistent pressure applied to the rod when a fish shakes its head and thrash around in shallow water...
If you need to pull the rod back enough to form a teardrop shape curve...maybe you should be using more adequate equipment to pull fish out of current...something with a little more backbone and a little less spring...
