Card of the opposite color is a great place to start. If light wood, dark background, light for dark. Helps you keep the edges in view. Get a clip flood or some such so you can get nice directional light to keep the real edge, not some shadow in sight.
Slow is still smart, but it can be frustrating. There's no "just right" here, but there is a "just wrong" speed. That's the one that won't allow you to pull back in time to compensate for follow as you depart the wood for air, getting you in smack and crack territory on the leading edge of the next wing. I think this is why people want to go faster. Personally, I am overhand grips and rest-hugging all the way. I keep reminding myself not to push.
Your choice of gouge can help you. I stick with the large-radius types on their edges, where a too slow retract will push the top of the gouge away rather than dig in when the next wing comes through. Staying above centerline outside is bright, too. Same reason. Inside goes below center so a falling hand will hit air, a press will push clear.
I like pivot entries here as well. Some turners don't even recognize what I'm saying, but it's a full body pivot to move the nose of the tool from no touch to the high-angle high-risk entry without moving your small muscles. Shift body weight and scoop through. Safer, because the pivot has you already established on the way out as you begin.
