Summary:

We ran the 7 pattern test with zeros at 40. We shifted the thresholds for colors. Results are not bad.
Really bad tiles: ew/pp/tt = -1/3/25,   -1/3/29,    1/6/1,    1/6/4
Concerning: -1/2/24, -1/2/28, -1/3/28 , -1/3/31
Board EQ2Db8 to be replaced.

===========

Vped for zeros: 40

Zeros: 26075047
Pattern 1: 48
Pattern 2: 49
Pattern 3: 50
Pattern 4: 51
Pattern 5: 52
Pattern 6: 53
Pattern 7: 54

We changed the thresholds for "colors" to:
< 50: blue
50<x<200: green
200< : red
The results attached. Does not look bad!

The board EQ2Bd8 will be replaced. which correspond to tiles: PP5-7 TT2-5 + PP01 TT06

Bad tiles except of board:
bolded: bad in pattern 0.

ew/pp/tt = -1/2/24: in pattern 7: 0, pedestal ok
ew/pp/tt = -1/2/28 in pattern 7: 0, pedestal ok
ew/pp/tt = -1/3/25
ew/pp/tt = -1/3/28 : in pattern 7: showed 277 inseted < 200, pedestal ok
ew/pp/tt = -1/3/29
ew/pp/tt = -1/3/31 in pattern 7: 0, pedestal ok

ew/pp/tt = 1/6/1 - zero always, reported in 2024
ew/pp/tt = 1/6/4
ew/pp/tt = 1/9/24 - about 50-70, should be 200+
ew/pp/tt = 1/9/26- about 50-70, should be 200+
ew/pp/tt = 1/9/27 - on the edge of color threshold
ew/pp/tt = 1/9/30- about 50-70, should be 200+
ew/pp/tt = 1/9/31- about 50-70, should be 200+
