Would you be pleased if this is how it turned out?

No idea! Low are on Friday (according to their website) and Kraftwerk can't play Saturday due to All Points East. GM tweeted that Low and Beach House aren't clashing.  Doesn't mean Kraftwerk and Low will definitely clash though. 

Do the ??? indicate there are a few more to be announcemed? I still hold out vague hope of the Bonny Light Horsemen joining us. I think it works on their currently announced schedule. 

i think there are a few more to be added yes.  Might be a few cancellations and therefore replacements as well.  The Clashfinder is based on last year's schedule but this year may have different number of acts so might not be any additions (other than the acts doing the Rising competition). 

How accurate is this version at this stage.  Already a major clash between Viagra Boys (lovingPunk Rock Loser) and Ezra Furman.  Just started listending to Ezra's new stuff (thanks to radio 6) and it is outstanding, she certainly has not stood still in re-creating her musical style (even though I also yearn to go back to the first performance I saw at GM).  
had been set on the full ViAgra Boys set, now it has to be Ezra, even if lower down the MainStage billing rather than a Far Out.headliner

It's not accurate.  It's all guesswork at the moment based on announcements that have been made by artists/bands.

Ezra is playing on Sunday.  Viagra Boys are playing either Friday or Sunday.  If Viagra Boys are on Sunday, it still might be the case that they are playing on the same stage as Ezra or at different times!  No need to worry yet! 

Thanks, not too dire yet and silly to worry about clashes which may not happen.

just wondered whether there was some insider knowledge invokve 

Nah no insider knowledge!  Quite a lot of acts have announced which days they're playing though so quite a lot of the days should be right it's just the times/stages which are not possible to predict.
