How to reset flight speed?

Thanks so much for fixing the ISO bug, but testing that fix brought up another question/problem.

I ran a mission to test ISO originally a few days ago, and I aborted it after a few photos because this was just a test.

Today, 3 days later, I ran the same mission, and Map Pilot Pro wanted to start over at the "abandonment point." This behavior really doesn't make sense now 3 days later. But I managed to get it to start over at one of the corners of the area.

But then after it got to the start point, it said (something like) "adjusting speed to 2m/s to match previous photos."

A few issues with all of this:

1) It would be nice if one could erase the saved state in a mission (abandonment point, etc.) and start over at the beginning. The only way I can figure out how to do that is to edit the mission and save it as a new mission.

2) I don't know why the program wants to match the flight speed of previous flights. If, for instance, the ISO for flight 1 is 100 and shutter speed 1/250, but the ISO for flight 2 is 400 and shutter speed 1/1000, the flight speed (to control blur) should adjust. The same if the first flight is cloudy, and the second sunny. I have now turned off the "adjust flight speed to control blur" setting for just this reason, but I really think that there is no reason to maintain flight speed between flights of the same mission — it should recalculate the flight speed according to the shutter speed for each flight.

Thanks for all your care in designing this program!

It must have been a lower light situation or the approach to the starting point must have been dark because the app detected that longer exposure times were being used which can cause motion blur. This is there to keep your images from becoming a streaky mess but you can turn it off in the Settings if you want. 

1. You can hit the unlock button to clear any past progress. 

2. The app wants to match the flight speed of the previous flights because the images are taken with a camera with a rolling shutter. This makes it so the footprint being imaged on the ground is stretched differently at different speeds. Mixing this stretching is not ideal and can cause processing inaccuracies. This is why we don't REALLY like people messing with the ISO settings unless they fully understand what is happening. Long exposure times leading to smear of more than 2X the GSD is the best way to ruin your whole dataset.
