Do potions really make a difference to training?

I've been training range and mage at the abyss, naturally bringing super ranging and super magic flasks.

But does anyone know how much these pots actually help with xp per hour? I've not done any proper testing, but having quick looks at runemetrics, the xp/hr based on a 5 minute running average, I've seen very little difference when potted vs unpotted.

For example, would it be more efficient to just bring prayer pots instead and pray t70 or t95 prayers?

I'm interested in people's thoughts/experiences or if anyone has properly tested this!
