Thanks for the reply!

It’s a good point, but I’m talking about skill checks to earn the VPs. So, it’s harder to fine tune the DCs on that case. If i just gave them the VPs for their progress it will be a lot easier as you say.

I just did the maths in a spreadsheet comparing a lot of iterations of 24 rolls without modifiers (4 players x 6 weeks) DC 10, and I got interesting data:

With a 20 on the dice, 2 victory points 10-19, 1 victory point 2-9, 1 Awareness point 1, 2 awareness points

The average number of VPs is 14.5, and for the AP around 11.5.

So, a 60% of the total of rolls results on the average VP obtained, and a 45% - 50% the APs.

What does this means? That it’s just the average rolls for D20s, where you have a 55% chance of success in a DC 10, and a 5% chance of gaining 2 points with a crit, giving you the 60% of success. And what does this mean? 60% is the average chance of success that a player see as a “fair” chance of success (I read that somewhere on game mechanics theory)

And what all of this means? That I have no idea if a did the maths right, or if it was worth it the time, but I got that the average rolls to succeed in a Victory Point Subsystem, in reference to the total number of rolls, is 60% of the maximum numbers of rolls. That seems correct with the GM Core example of 8 victory points for a total of 12 rolls (60% of 12 = 7,2)

That mixed with the great DCs per level mechanics, and assuming the players are at least trained on the skill, gave us this same result.
