Total time estimated for work

im running the 0.8.07 version of lightburn, when I create something and want to send it to the laser, and preview to see how long it would take, for example; on the preview box would said that the total time estimated would be 30 minutes, but when i rung the job, its taking more that 8 hours. i don’t understand what the issue is, any help would be great.

It’s not an accurate estimate at the moment but it is being worked on.
