You adjust the slider’s controlling bandwidth percentage. And as you make the adjustments you then perform the wave form test on til you’re dialed in. Check your dm.
Congestion control, adjust until the wave form test shows an A+ result with 0’s. Keep an eye on the jitter, you want that as low as possible (0.8 or lower).
I've noticed low jitter equals better hit registration. But the only firmware versions that maintain the low jitter after adjusting congestion control are .227 and .236. Every version since the jitter drifts upward after dialing it in.
