Quoted from Yelobird:
What lights were removed missed that post? Guess you will see when you get your game and set it up to your preference. All anyone is doing is showing you what you can do if you would like to improve it. As for “just removing a screw”, it’s 18ga stainless steel not rubber. Removing a single or over several screws will not make it suddenly bow as a ball passes. Trust me I tried that lol. All good and loving the game now.
Quoted from Troz:
I had to loosen the wood rail to get the post underneath for the curvature I wanted, plus I had to remove one LED :/

I think you'll find the removing screws is allowing movement you can't notice, but is there.
Consider a hard steel ball on a hard solid steel block. If you drop the ball on it, the ball will bounce. The energy is sent back. No real "give", but the material is still "springy".
Then the same hard steel ball dropped on a hard steel sheet, overhanging and Not supported from below (the impact zone)..... the impact of the ball, the energy, is absorbed in the movement, or "give". A dead blow, that doesn't "bounce" (or bounces Significantly less, at least).
By screwing the fairly thick ball guides down with many screws makes a "rigid" and less giving wall. It is firm, and energy returns to the ball, "bouncing" it off the guide.
Now take a heap of screws out so that some flex can absorb/store energy as the ball impacts, meaning it would bounce less on the guide (if at all), and follow it. The guide returns gradually after the End of Impact, with some energy gradually being returned to the ball on gradual return to shape. ie. less per rate than the centrifugal force holding it against the guide.
Someone else described it quite adequately a few pages back. Repeated here with different words. The impact is dampened, spread. There is a "time" consideration that varies too, absorption, duration, reflection, stuff, things ... Lol
I'm all on board with some screws being deleted, especially when it is endorsed by the engineer responsible for the game.
I don't think radical ball guide alterations are warranted at all.
