Basically, during the 15's the reps should start out slow and then speed up as you feel the burn begin to kill your strength. After all, the whole point is to flush the muscle with lactic acid.
During the 10's you should go slower when the weight is light. That way it will still be difficult to complete the set. As the weight gets heavier simply increase the tempo to ensure that you complete the set. BE careful not to get too sloppy though. It will do little good to use momentum to move the weight during the 10s.
The first week of 5's should be slow on the way down but still pretty explosive on the way up. Then as the weight nears your 5 rep max you will have no real control over how fast you move the weight. It will generally go slow simply because it is so heavy.
During negatives you should lower the weight in about 2-3 seconds. This may seem too quick to most traditionalists. Research has shown that if you go too slow during negatives you don't get the same growth stimulus. it begins to resemble the effect of isometrics if you go too slow. This is one reason why the old principle of "time under tension" isn't so simple as just time. The action of the muscle while under load is very important when trying to produce a specific effect.
