A yellow wizard calls for aid 10 minutes after entering runespan and 10 minutes after you've given him runes, so 5 teleports should be
slightly
over an hour (as some time will be spent teleporting and handing him the runes every time before resetting the timer).
And I'm not too sure about the xp... usually 300k+ a day for the extended challenge since I have bonus xp in rc and master rc robes + occasionally I'll get xp lamps from using the dwarf instinct aura at the same time.
Yesterday I got 242k as I kinda forgot about it and barely managed to complete the challenge before reset (and didn't use all ethereal teleports before heading to do guthix cache)
