Related question to the above: Does anyone know when the window is checked for mooching? For example, using the Twitchbeard example above, could you catch an HQ Fullmoon Sardine at 2am, wait six minutes to hit the mooch button, and have a chance of getting a Twitchbeard? Or does the initial cast in the chain need to be made in the window for the final fish to have a chance at it?

For fishes that require mooching and have tight windows, I've been trying to get in an extra attempt by pre-catching the HQ base fish. I've only done it a couple times so far, but it hasn't worked yet. Wondering if I'm wasting my time trying to do it :P
