Tip 1: Only mark fresh eggs

This is the first in a series of posts Vicky will be publishing in which she shares some tips for accurate worm watching based on the annotations she’s analysing.



Hello once again, Wormwatchers!

To continue on from the Top Ten graph in my last post, here is another graph giving the number of users recording times in a 30 second video containing only one egg-laying event. Here is the link to this video:

The red dotted line marks the time of the egg-laying event. As you can see, most users press ‘z’ close to the actual event, but a few users seem to go astray.

Help is at hand! From now, I will be posting tips to help you on the way to becoming a professional Wormwatcher!

Tip of the day: Do not mark eggs that are already there!

It’s very tempting to press ‘z’ when you already see an egg, but ONLY press ‘z’ when the egg appears from the middle of the worm while you’re watching. Have a look at 0:27 of this video where an egg appears next to the red spot:

There are already two eggs at the start of this video, and these must NOT be marked.

A few of you go into a clicking frenzy as soon as you see one egg. Only click ONCE when you see ONE egg-laying event. Rest assured that the time appears on the right hand side of the video and it is recorded. If you see another egg, press ‘z’ once again to record the next egg. If you make a mistake and accidentally press ‘z’, you can remove the time by clicking the cross next to it like so:

Happy Wormwatching!
