LOL, Roly !You spoke no truer words. You need to trust your judgement and know your every move is controlled by holding down on your project as you cut .The saw only can cut what you let it, Having a fish handshake,loose and uncontrolled hold of the wood is asking for mistakes cutting.Trying to stay on the line completely and make time is very nerve racking and tedious.When i cut fast ,I'm not always on the line but no more than a pencil width's away from it.If i wander i feather it back to the line as i go. Every word letter i do is full of wanderings .Yes you can tell ,but only with a microscope.who ever looks at my work will never know i made lots of mistakes.And when i finish i knew where i made wanderings and mistakes but cannot even pin point them out to my self.Don't worry about details ,Only on facial expressions is where i worry about details and even then not that much.Straight lines and corners are the easiest to do . Circles are the hardest and 11 years of doing them i have to go slow to do the best i can.the worst thing you can do is try to stay on the line .I will hinder your scrolling time,frustrate you and not produce that much better a product than not .The eye is not that discriminate from a distance to find flaws,I use all my finger in sync with my eyes and brain to where it's second nature cutting letters .I wish i could stop to watch my fingers all move when cutting as it amazes me the brain can control them all in a mili second .I really think i have no control of it all somehow. As i cant walk and chew bubble gum at the same time .I think it's a gift from above!
