This is the BBC.

No, on BBC Radio 4, it's time for more or less.

Or one moment, I do beg your pardon, that doesn't look like Tim Harford.

Hello, I'm Roger Bolton, and in feedback this week,

we'll be trying to get to the bottom of a water temperature problem on more or less,

which is turning loyal listeners against the programme and each other.

It's a bit embarrassing for a programme about numbers to make an elementary mistake

about the temperature scale.

I was on the verge of throwing something at the radio over the patterns who were,

pointlessly, noting that 30 degrees is not twice as hot as 15 degrees.

Also this week, the use of music on Radio 4 has long been an irritating issue with many listeners.

We ask the producers of more or less to justify their use of it.

Thank you for playing sad music underneath the Grenfell Tower Fire item.

Without it, I may not have understood just how sad a story it was,

and that I should feel sad.

And finally, has Radio 4's Mr Ruud?

No, not John Humphreys, his successor, Tim Harford, gone too far this time.

We have a cascade of complaints about, more or less.

Hey, hey, Roger, you're in my seat, and you're in my slot.

This is more or less feedback, not on air to October. What are you doing here?

Well, it is our time slot, and I'm in the building, and I'm bored at home.

I want to do some work, and there's plenty to do.
