Extreme issues creating match schedule (for event with few teams)

[pmichaud]

Describe the bug
At several of our league meets we've run into extreme difficulties trying to set up match schedules, where setting up match block times behaves badly and is time-consuming/error prone. Spurious "breaks" get added, it's difficult to set match block times, and sometimes small changes to a match block cause radical changes to the full schedule.

To Reproduce
Steps to reproduce the behavior:

I found it difficult to write text with the steps to accurately document/reproduce/describe the behavior, so I created a
short (6-minute) YouTube video to illustrate the issues. https://youtu.be/I68LUmDR_NM My apologies if this is an inappropriate way to describe the problem.

Expected behavior
Setting values in match blocks should not cause radical/unexpected changes to the entire schedule.

Screenshots
Rather than screenshots it was easier to create a video: https://youtu.be/I68LUmDR_NM

I observed the same issue generating our schedule on Saturday. It took us several attempts to create a typical schedule.
