A. Measuring Success

1. If Task Throw <= Governing Stat, then Greater Success.
2. If Task Throw <= Difficulty Throw + Stat, then Normal Success.
3. If Task Throw > Difficulty Throw + Stat, then Marginal Success.

B. Measuring Failure

1. If Task Throw >= Difficulty Throw – Stat, then Normal Failure.
2. If Task Throw < Difficulty Throw – Stat, then Greater Failure.
3. If Task Throw <= 0 (due to the E-Die or DM's), then Mishap!

E. Should We Tell The Players?

For instance, when meeting and dealing with other characters (especially NPC's), characters may try and estimate the UPP stats of the individuals they meet. Here are some suggested estimation Task Throws (as adapted from the MegaTraveller Referee's Manual):

To estimate a physical stat (STR, DEX, or END) of another character:

Average, Medical, INT
Referee: roll once per physical characteristic.

To estimate a mental stat (INT or EDU) of another character:

Average, INT, EDU
Referee: roll once per mental characteristic.

To estimate the Social Standing (SOC) of another character:

Average, Liaison or Streetwise or Bribery, INT

To estimate any UPP characteristic (STR, DEX, END, INT, EDU, SOC, and LIF, DET, EXP if these are used) of another character:

Average, Interview, EDU, 5 min
Referee: roll once per characteristic.

To estimate another character's skill level by observation:

Difficult, [skill], EDU, 5 min (unskilled OK)
Referee: the skill in brackets is the observing character's level of the skill being estimated (or a related skill).

Referee: for ANY of the above tasks:

If the result is any sort of failure, misrepresent the stat or skill by 2D – 7.
If the result is Marginal Success, misrepresent the stat or skill by 1D – 3.
(In all cases, treat a stat estimate of less than 1 as 1 - unless the character is unconcious! - and a stat estimate of over 15 as 15; treat a skill estimate of less than zero as a belief that the character has no skill at all!).
If the result is Regular Success, provide the player with the correct value.
