I did a 4*40 ARF in about 8 hours and 2 SIG Somethin Extra kits in roughly 2 weeks each working 3 to 4 hours a day not including the covering.

I know of 2 people that did the 60 size KIT (not the ARF) in about 2 weeks working the same as I did with the SSE's so say about 20 hours not including the covering
