Inverse Crescent. You are drawn by a gradually increasing force towards MC. The measurement of the force (which we will call "Pull") is basically -LV, but it does not increase at a uniform rate. This is probably due to quantum. (The technical specialists among us can expand on this.) Periodic announcements on the current level of Pull will be made by Mission Control. The aim is to resist the increasing attraction to MC as long as possible. The higher your LV away from MC, the longer you can resist, but if your LV becomes greater than 186,000, then you break free of Pull altogether and spin off into outer wotsit, ending up god knows where. The first person to arrive at MC, obviously, loses the game.
Wobbling at Walthamstow, with LV jumping between 9.085 and 11.23 - I think the Piccadilly breakdown must have increased quantum on the Victoria. MC] Is there naan bread?
Wheeeeee! Hurtled past the Great Station without even a momentary hesitation. The slingshot effect has put me out to the comparative safety of Eastcote with LV only marginally increased to 23.33333......
Damn! Held at Baker Street with a dangerously high LV of 2,750, which can be maintained in geo-statis only with the careful application of a buttered cat and a tall stepladder from which to drop it, thus creating a source of perpetual motion, and saving the LV Potential for use when the rush hour is over.
