Two short morning sessions where I fish a few different swims and get about the pool to try and find the carp. As the sessions go on it gets harder of course. As the number of fish caught increases the number uncaught decreases but not only that. The ones you catch at the start are usually the easiest to catch so not only is there less fish to catch but the ones left are generally also the most difficult to catch.
We are going into that zone now six sessions on.
