There have been similar conversations about this chrono before.
For people who use public ranges and do not want to cause a disturbance to others by fussing with a traditional chronograph, the MS is a good alternative. It is also faster to set up and tear down.
It is an option that some people will find suits their needs.
If you wish to shoot, measure velocities and find an accurate load at the same time, a Pro Chrono or similar is a better choice.
Life is often a series of trade offs. The MS allows you develop loads first and measure velocities later.
There are actually people around who have never owned a chronograph, but manage to take game year after year. This group demonstrates that having a chronograph isn’t necessary. A reloading manual is however.
It all boils down to time management.
