Question about gender-help

Is it quicker for a ultrasound tech to see boy before girl?

When I had my 20 week scan the tech went down to the potty shot so fast I didn’t even have a chance to see the image before she was done. I asked her did she see the sex and she said yes it was plain as day.

So that is why I’m curious is it easier for a tech to spot a boy first before a girl ?
