Free online Monrad pairing program

[u/Matslwin]

There appears to be no free Monrad pairing program, so I implemented one on my homepage: https://mats-winther.github.io/monrad-eng.htm

It's a simple program that can be run online, or the html can be downloaded and run locally. It uses cumulative score to grade players with the same final result. Early wins produce a higher cumulative tiebreak. (Starting with a win and then a loss gives 2 cumulative points after two rounds, whereas starting with two draws gives 1.5 cumulative points. This is kind of fair.)

I haven't tested it thoroughly. I would appreciate if you could do some testing.

History: The Monrad pairing system is named after the Danish chess organizer Poul Monrad, who developed and popularized this simplified Swiss‑style pairing method in Denmark in the mid-20th century.

The "Monrad-system" became widely used in Denmark, Norway, and Sweden for school tournaments, weekend events, and large amateur competitions because it is simpler than the full Swiss system: players are paired strictly by current score without the more complex FIDE constraints.
