has anybody heard this before?

[LANGER]

i was told the other day by a guy that i always thought of as a pretty educated bass fisherman, that when you catch a fish that is just under the length limit (like a quarter of an inch or less ) to go ahead and keep it. he said that during the fight a fish will tense up and kinda cramp a little, but once in the livewell it will relax and gain that length right back. never had the guts to try it but i was wondering if it was a myth or if it really works.
