I agree completely, my 305 instant pace never varies much. I had the first Gramin Forerunner 101 and loved it, pace worked perfect which was why I bought it. I now use a 305 but thought about passing it down in the family and getting a 110 but having only an average pace does me zero good so looks like I’m buying a 310xt. I tried a 405 and just didn’t like the bezel controls.
