I have sent J&C my times for some of their films in WD2D+, but have not yet tried Classic 200 (though I have some sitting here). Basically I found a good starting point for WD2D+ is to take the time for whatever film in D76, and then if it is straight D76 add three minutes, and if the listed time is for D76 1:1 add one minute to the time. This so far has gotten me nicely in the ballpark with EFKE 25/50 and J&C100 for negs to be enlarged (35mm and 120).
Hope this helps.
