I agree totally La mer, except the ones I've presented here were actually carried out week by week over 12 Saturdays and were not back-fitted.

I don't own and would never buy a stats data bank. I'd [also] rather watch paint dry than sit around with a data bank [if I had one] working out rules to fit past results. However, each to their own and I'm sure many get hours of pleasure doing just that. Who knows, they might even make some money from it[?] Not my cuppa chow though.
