Hello, Folks. I'm totally new on this great interactive encyclopedia of gymnastics lovers. Have 3,5 months of rings training. And have one bothering me question. Small digression, at first: sorry for my mistakes, cause english is not my native. I'm — from fareast of Russia.
All 3 months of training were proceed on rings in my workplace office's warehouse. There were straps from point of attachment to the rings in about 2,5-2,8 meters (9 feet) long. From this three months have achieved next skills: solid muscle up without kipping (a bit slow, cause the transition part from pull to dip is still demanding, but solid), L-sit, clear back lever with pullout without any pike, one-leg front lever with pullout, 3 front rolls to support in a row, front kip to support, rare back kip (or feldge) to support with pike, handstand using cables, totall solid 50 degress (lacking 40 to full) iron cross with pullout. So, i think not bad basement. Maybe it would be usefull to say that before rings there were 4-5 years of rock climbing.
The position in RTO support and Iron Cross are super solid, maybe having a tiny little swing in direction face-back, but totally no wobbling in straight arms (necessary to say that i'm just fanatical in controlling that hands are really totally STRAIGHT in all skills wich demands straight arms such as cross and levers).
And now me and my frined which has also felt in passion with rings have moved to local climbing gym, where we have set up the rings as they "should be" — about 3 meters from the floor (2,8 if counting the floor-mat) to have ability to try the swings, inlocates/dislocates and flyaway, about 1,2 meters of straps from rings to wire cable, and then the wire cable to the place of attahcment.
So now the real distance from the point of attachment to the bottom inner part of rings is about 4,5 meters (12,5-13 feet).
What i have found - the muscle up has come sensibly easiaer (moving hands much far apart from body and much less pike while transition), BUT....... Even the holding RTO support without wobbling became REALLY HARDER. And i even couldn't take the wobbling away totally. No matter how solid became i (contracting all muscle which possible) there's still visible wobbling when arms are totally straight. Just a little tiny bent in elbows, of course, stabilize everything, but hey we know that this is not "our way of doing things on rings" 
The L-sit and Cross also became MUCH harder. The cross angle have decreased to deplorable 35 degrees and i'm shacking holding it like a leave on the wind.
So' i'm wondering should i or shouldn't... Have such an idea - connect the cables from rings with a thin steel chain on the distance from rings which is declared in official FIG rules for gymnastics events - something about 3 meters ( 8,5 feet) to make closer to perfomer the real point of attachment from which rings are going sides when doing such things as cross.
What do you think?
ps: and what about just modelling the situation when we have, for example 50-100 meters long cables from point of attachment to rings. Would it become almost impossible to hold a cross for a gymnast who's doing it easy on standart "correct" FIG rings?
If not joking, really sure that all stuff delivered to things like different crosses (and any other holds like correct nice RTO L-sit when hands come even a bit to sides from torso with palms really trying to look forward) is covered in altered angles between your arms and points of attachment.
