Pete is, of course, correct. Cedar Point did nothing to the Blue Streak, and in an extremely methodical poll, the coaster was ranked at a respectable #11. Since the Raven joined the poll in 1995 at #2, for the Blue Streak to maintain its #11 ranking means it actually did better in 1995 than it did in 1994, though it was ranked the same.
In 1996, Cedar Point butchered Blue Streak's trains and installed a computer. Blue Streak went from 'fun' to 'painful' in a single season, a change which was immediately reflected in the poll ranking with the ride's fall from #11 to #29. As more poll participants rode the "new and improved" Blue Streak, the rating went into a sudden free-fall. It recovered slightly by remaining at #51, but only very slightly.
The moral of the story? If it ain't broke, don't fix it!
