200 mile errors out 5 days is actually very good. 20 years ago, errors were actually larger than that in only 3 days. I think if I did a plot of 48 hour projections, they haven't been that far off. The other day I looked at where they expected it when near Cuba, and they had it just inland. I think it passed about 50 miles west of that point today. Time-wise, I wasn't checking, I was just looking at location.
I made a reference in an earlier post that they used to put at the end of their 3 day forecasts back then "errors may exceed several hundred miles". I guess it is all relative, and perception.
