I have a few questions about the calloway v  ramp.

  After having watched some vids on youtube of these ramps i'm curious if what is shown is valid.

http://www.youtube.com/watch?v=3r2aZ3llqok&feature=related  this has a triple v ramp,

  the questions and query below only involve a single v ramp.

  The magnet that travels along the ramp is shown to travel forward from a standing start when released anywhere inside the ramp. True/false
  It will also travel forward when released a small distance before the ramp entry. True/false

  watching the vid, it breaks free of the sticky point when it is released before the ramp
 I assume this is because of the extra speed gained, creates enough force to escape the force at the sticky point.
   
  usually in these vids the ramps are short, they only have 1 -3 magnets on the carriage that enters the ramp,and have always wondered what would
happen if there were more magnets on a longer carriage ( say about 95 % the length of the track)  a longer ramp, and the carriage being released within the ramp.

 My logic is probably flawed but,
assume that it would take a 1kg pushing force to break free at the sticky point,
would making the track longer, and having more magnets on a carriage, that for this example is almost as long as the track ( but is still all within the track)
create enough force so that the leading magnet on the carriage breaks free of the sticky point.
 
e.g. hypothetically, say the track is 1 Km long, and there is only 1 magnet on the carriage for every metre, each magnet would only need to create a 1 gram push force to
be = to the sticky point force.
  Now lets place a magnet every 5 cm on the carriage, which would = 20 kg of force if every magnet only had 1 gram of push force.
  I would assume the push force of the magnets would be greater than 1 gram. I have not taken into account the friction of the carriage
but if the above example was valid, the ramp  would be placed on a wheel.
  The 1 km ramp is only an over exagerated example, used as a way of finding out if the combined force of magnets in a ramp can be greater than the sticky point force.
 I want to know where my mistake is, in this type of (probably stupid) logic.

 Any advice would be of great help.
