On a run (mainsheet in hand)

[JuanCH]

Hi all! This new format looks pretty cool. Ok here is my doubt. Today I went sailing (7-8knots).
When I was on a run I had the sheet in my hand, I grabbed it in front of the ratchet so I could feel the pressure of the sail. But whenever you feel that pressure is starting to grow, what am I supposed to do?? Should I ease the sheet a little bit? Should I bear off a couple of degress?? Thank you all!

Assuming the leeward mark was set directly downwind of the windward mark, typically in that velocity, you are sailing angles, ie a little by the lee or slightly high of the mark.
When you feel the puff (thru the pressure in the sheet), you want to start heading directly for the mark to maximize VMG (velocity made good towards the mark)
