I noticed this at my local as well, and most importantly, at our track carnival, and regional champs. Our club was a mish mash of new and older guys, and looking back, I'm suprised that some of the more experienced guys didn't suggest some tactical plays. For the longer 10 lap (397m track) races, we really should have worked together. Prizemoney was on offer, so I would have been happy to split with others that did work.
I was more a victim of team tactics at the regional in a 20 lapper (same track). There were only 2 of us from our club and 8 from another. My "team mate" couldn't keep up, so I just mixed it with the other club. I got sling shot off the back during the rotations, but was able to keep the same pace as the lead bunch. After a couple of laps I was able to close the gap slightly. One of the other club riders hung there with me, but when I tried to rotate with him he slowed down noticeably. But when I took the lead, he stayed with me. In the end I knew I just had to do it myself (my Cadel moment) Didn't manage to get there in the end, but came in 4th overall as more of the other team dropped away.
I put it down to a lack of experience being my first season, and now about to head into my second I am more educated and wiser. I have begun my journey up the learning curve.
