That's not true.
I run 46 : 16 and I can do nearly seated skids fine. Once your muscles get used to it, the getting up and leaning motion doesn't need to be exaggerated as it was when you were learning.
Basically anticipate your momentum when you are riding. If you are going fast, and spinning at a higher rate, lean forward earlier so that you can time the cranks at the 9 and 3 o'clock position.
Keep practicing leaning forward less and resisting the pedal stroke (muscle!) while your legs are locked.
Eventually, you'll get to a point where you only need to get up from the saddle a for an inch or two and lock/skid perfectly.
I also found (from someone here), that it's much easier to control if you squeeze your knees together at the heattube/frame while you're skidding.
Another thing you can try for fast skids is get up out the saddle quick, lock, then try to sit down immediately after. That way, your legs are still locked and the sitting down motion helps with resisting the cranks. You have to do this really quickly though. This is best for quick stops.
Hope this helps.
