Our club has organised a Patton tournament. This is a great scoring for short team-matches, so it enabled us to play 10 rounds of 4 boards.
Preparing for the tournament I found a conversion table on the internet for 4 boards like this:

IMP | VP
0- 3 | 4-4
4- 7 | 5-3
8-11 | 6-2
12-16 | 7-1
17+ | 8-0

The scoring program of the NBB (Dutch Bridge Association) however uses a different conversion table:
IMP | VP
0- 2 | 4-4
3- 6 | 5-3
7-11 | 6-2
12-17 | 7-1
18+ | 8-0

It seemed obvious to use the NBB conversion, that's what we have them for don't we?

The BAM score was easy:
0-20 | 1-1
30+ | 2-0
0-10 | 1-1
20+ | 2-0
But someone suggested to change that to
0-10 | 1-1
20+ | 2-0
0 | 1-1
10+ | 2-0

Now I'm wondering if there is a standard for Patton scoring and where can it be found.
Or is Patton just a guideline with liberties for the tournament organisation?

Corrected BAM scoring

Strange, the method I'm familiar with is completely different. It considers 10 difference a tie board but not 20, as per the suggestion you got. The other component is scored not by IMPs, but by total points, and for a 4-board round there are only 4 points available. 4-0 is, IIRC, beating the other team by 500+ total points, don't remember the cutoff between 2-2 and 3-1.

I made a mistake in the BAM table, corrected now.

The total points you have played by adds to my confusion.
Apparantly Patton has many variations.

The WBF formula would give:

IMP | VP
0- 2 | 4-4
3- 7 | 5-3
8-13 | 6-2
14-22 | 7-1
23+ | 8-0

I think it used to be quite common in hybrid scoring methods for 10 to count as a draw, though I haven't seen it extended to 20 before, but increasingly this seems to be changed in line with strict BAM scoring where only 0 is a draw.

I never understood forms of BAM where a difference of 10 was considered a tie, if you want to play a form of scoring where margins like 10 are not significant, play IMPs!

Well, with hybrid scoring, you are playing IMPs.

I think that 10 has usually been counted as a draw because it is already pretty complicated for the player when you have two different objectives on every hand.
