I hardly trust LSRs anymore, unless they're for flooding roads as it's hard to mess up that report. I've been pulled off a cell once or twice because a spotter claimed to see something and it ended up being a very dead cell. My fault for not trusting myself, but still a good lesson to learn. "Trained spotters" reporting .25" hail, reports of UFOs, LEOs parked next to tree lines with funnels forming just on the other side... my point is to just exercise some caution in accepting others' reports at face value because not everyone out there calling things in knows what they're doing.
Also, if someone else already reported a feature, why would you report it again unless you had evidence counter to what they were reporting?
Everyone makes mistakes and especially in weather. Just look at Dr. Wurman's recent chase record
Seriously though, people won't judge you based on the mistakes you make - they'll judge you based on how you handle them and how you learn from them.
