IN YEARS PAST, IT WAS VERY HELPFUL IN ANALYSING POTENTIAL ERRORS IN THE IELD, TO CARRY AROUND WITHIN YOU,THE KNOWLEDGE OF WHAT KIND OF POTENTIAL ERROR WOULD YOU HAVE IF, SAY 1 MINUTE OF ANGLE VARIATION MEANT THE POINT WAS OFF LINE APPROXIMATELY 0.03' IN 100'. AND 0.30' IN 1000', ETC. NOW FAST FORWARD TO TODAYS LAT/LONG. WHAT IS THE POTENTIAL ERROR (IN FEET)FOR EACH DIGIT TO THE RIGHT OF THE DECIMAL POINT FOR EACH LAT/LONG (SAY IN COLORADO)? I.E.,
39 40 50.X DIFF = ________ FEET
39 40 50.XX DIFF = ________ FEET
39 40 50.XXX DIFF = ________ FEET
39 40 50.XXXX DIFF = ________ FEET
39 40 50.XXXXX DIFF = ________ FEET
39 40 50.XXXXXX DIFF = ________ FEET

JUST NEED THE DIFFERENCE AND NOT A LONG EXPLANATION OF WHY IF YOU ALL DON'T MIND. THANKS AHEAD OF TIME.
