Hi,
Better too loose than too stiff, definitly. A rule of the thumb: bike on
side stand: 10cm freeplay. 
When you sit on the bike and hop around, the chain should always have some
play.
>>> I could feel the free play of the chain
If the chain is old (and worn out) you feel play even with correctly
adjustet chain free play. You won't get away that by adjustment, only by
changing the chain and sprockets. The cause is, that the bolt/"ring" inside
the chain already have too much  "play". You can test that, by trying to
"pull" the chain off the rear sprocket. If you can pull "one piece" a
"teeth high" -> ready for exchange :-)

From the experience of a "hard working chain" (driving nearly all time with
socia, very brutal driver :-)): the chain didn't lenghten for the first
15.000km, not even a bit. Starting with 18.000km, the chain needed a little
adjustment about every 2.000km. At 22.000km, the chain suddenly started to
need adjustment every 200km (!) -> exchanged that lousy one :-))))

have a nice slide, Martin
