10 place penalty for each new engine.
Does this mean that they could take a new engine in Race 16 (say). Then start 10 places down on the grid.
Then use the same (1 race old) engine in Race 17 and not take the penalty?
In otherwords, does the engine (grid place) penalty only apply the first time the new engine is used or does the rule apply to every race which the engine is used?
