Did Greg actually give preferential treatment to Rhod Gilbert?

The great question of our age. Sorry I realise this has probably been discussed to death, but I’m watching season 7 again atm and to me it doesn’t really seem like he does. But having read and listened to interviews with the other contestants they really genuinely seem to think he did. James, Jess, Kerry have all insinuated it in one way or another. Maybe it was more obvious in studio? Richard Herring even practically told Greg he had during his RHLSTP - to which Greg replied something like “well I’m sorry if that’s what it looked like”.

For my part I think that Rhod spent a lot of time ragging on Greg, which Greg didn’t retaliate to. Then you get James being taken to one side and mock-told off for being a bit spicy. So maybe he let Rhod get away with more, but points wise I don’t feel like he scored Rhod any higher.
