who needs accuracy in a pot, you adjust it until it is set correctly, only thing is stability, and for that i have found it to be enough for most projects i have done, where you want to dial in on a value, over a large range, e.g. low voltage threshold on a pump timer, the pot i used was a multi-turn because the circuit works from 2V to 50V, and its much easier to set a multiturn than a single turn 270 degree pot if your aiming for a specific voltage, and know the temperature will not shift much (18-33C)
