The variation parameter in the Delete operator will vary the age each particle will be deleted at.

It looks like you're looking for a way to fade out particles using opacity.

say you want to fade out your particles gradually from age 50 to 60, send them via an age test to a new event at age 50.

In this new event, first off put a material dynamic operator. Make sure to check 'reset particle age'.

To this operator add a material similar current material, but one that has a particle age map in the opactiy slot with which you can control the fading out (start at white at 0% age and black at %100 age).

After that add a delete operator, set to by particle age = 10. (add any age variation you wish).
