Why not? just want maximum,
sometimes has a purpose.
some aerosols are designed for it.

the purpose is to bend the bit so it runs wobbly in future. Only rarely useful to free a jammed bit.
with ones that aren't it's cheaper than buying freezer spray.

Are you sure she's not refering to point 2 regarding giving it a wiggle before withdrawing it. ;-)
I'll raise you to
- Apprentices that cannot tell the difference between a 110V and 230v task light. FFS five year old kids can play the old square, triangle and circle game of put the shape into the correct hole.
- Apprentices that can talk and breath.
- Their parents.
Posters who can spell. :-)

Oddly, mine does. As part of a weather compensated system. I've no doubt because I've never quite got on top of the programming. ;-)
Vaillant have a coupe of graphs that explain what their system does. The first:

Shows how you can tune the response to the characteristics of the house. Basically the response curve shows how external temp influences the flow temp the system self chooses. Choosing a steeper curve makes the response to falling temp more dramatic. So you choose a steeper one for higher heat loss properties or ones in exposed locations etc. (I find I need about 1.8 for our place - solid walls, somewhat exposed location)
The second one gets a bit more subtle:

The "axis a" slope is used to shift the whole selected curve from above, based on the target temp set by the room stat. So setting a higher temp on the room stat will result in the whole flow temp graph line shifting up and left. So the nett result is not only does a colder outside temp result in a higher flow temp, a higher room stat setting also equals higher flow temp on top of that selected just on external temp.
