The onset of tails can be seen in VM mode by a fluctuation of temp. It will be probably be only point one of a degree rise, but if your thermo has been rock steady on .7 of something (or flicking tween say.6 and .7 ) and then goes to .8, be ready to shinny up the ladder and wind your gate valve back in in order to extract the last of the hearts slowly. Once wound in to a small stream the temp should settle back to where it was for a half litre or so before starting to rise again. This is the point i usually give up.
Alternatively you may be able to shut the vm valve and crack the lm to bleed the last of the hearts, dunno never operated one, but it's a matter of learning to drive your own equipment.
Quite a few people use a mid point column mounted thermo as well to give early warning of the tails creeping up the column in the same way ;)
