Read fishing patterns without fooling yourself
Use catch history as evidence with coverage limits, rather than treating a small log as a forecast guarantee.
Editorial review: . Review due: .
Counts need context
Ten trout on a nymph and two on a streamer do not settle which worked better. You may have fished the nymph ten times as long or used it in different water. Catch count, completed trips and active fishing time answer different questions.
Keep your catches separate from clients’ or friends’ fish when interpreting personal patterns. Missing legacy trip links and partial history should remain visible rather than silently being assigned to an outing.
Ask a question the record can answer
Start with “What did I catch on this fly in October?” and open the matching entries. Compare water, method, effort and unsuccessful attempts before saying one condition produces better results.
A nearby gauge describes that station at its observation time. A saved weather value, an astronomical tide calculation and a future forecast are different evidence. Do not substitute today’s conditions for the conditions on an old catch.
Make the next trip a useful comparison
Write a small plan and record the outcome, including blanks. Revisit similar trips rather than only the best photograph. A larger log can still be biased if only successes are entered.
Fish Fish’s personal history views describe saved records. They do not establish a scientific bite probability or guarantee a catch. When samples are small or effort is missing, keep the conclusion tentative.
