For one way scoring only particles crossing the considered surface
- representing the boundary between two regions - from the upstream region
to the downstream region (input as WHAT(4) and WHAT(5), respectively) are
taken into account. Whereas two way scoring includes also particles
crossing the surface and coming from the downstream region.

This difference is definitely substantial. Current gives the number of
particles, while fluence is the tracklength density which in many cases is
what really matters. Please look carefully at the thread

as well as at the scoring lecture of the beginner course
