Improve

GURPS Martial Arts: Technical Grappling phrases the concept in various ways in different places:
*7 One has seized his rival by the neck and arm, for 2 CP on each location. On his next turn, he attacks to improve his hold on the neck
*11 Attacks to improve control of an existing grapple or to break free are allowed at -4 in all postures
**this refers to improve/break when Relative Facing of foe is in rear hex
*15 When used as a grappling aid (such as a whip or belt used to apply a Choke or Strangle) it requires both hands to attack and improve your hold
*16 The weapon requires two hands, both to initiate a grapple and when making further attacks to improve control
*20 Double: Make two regular attacks, including techniques that count as attacks. One of these attacks may be combined with Rapid Strike, allowing (e.g.) a grapple, takedown, and attack to improve position – all in one second!
*21 An Attack is used to initiate and improve a grapple, or to free yourself from one!
**21 Improve your control for an existing grapple. Add CP rolled to the targeted location.
**21 Attacks to improve position, break free, or apply joint locks do not suffer penalties for hit location
**21 You may always attack to improve your grapple
*22 You may attempt a Stop Hit with a grappling attack, either before a grapple has occurred or while trying to improve position
*22 Escaping Parry (p. 36) reduces the CP inflicted on you while parrying a foe attempting to improve his control by attacking an already-grappled location
*23 Escaping Parry (p. 36) is used to break free of a foe’s grapple as he tries to improve his position.
*28 It’s possible to attack to improve the grapple as usual.
*37 If many foes are fighting a single opponent, each resolves his own attacks to grapple or improve position independently
*42 You may not use Grabbing Parry if your foe is attacking to improve an existing grapple.
Escaping Parry on page 36 doesn't actually mention the word. Instead it says "attempts to create space from an existing grapple". Page 22/23 imply this can only done against Improve attacks, rather than being able to escape from a grapple while parrying an entirely different attack.
