Pulse Width is playing very important role in calculating debug numbers.
Initially PW was set at 150.
Than i checked the debug numbers by rising PW up to 220 and on each step i got better debug numbers and much calmer and more stable behavior.
When PW is set at 180 and above; detector behaves perfectly! Just splendid!
But be aware that this is the situation closely related to coil specs too.
If you get different behavior than it's probably due differences in coils.
