I made a new tool: Short Games Analyzer Tool
https://www.sp-cc.de/files/short_games_analyzer_tool.7zIt builds very detailed statistics-files out of the short games (up to 60 moves), engines or players played (out of a pgn-file of games).
The SGA-tool writes a statistics-file: SGA_full_statistics.txt
In this file, the percent numbers of all short games (wins/draws/losses, not longer than 60 moves) of each engine/player are stored (percents compared to the overall number of won games/draws/losses of this engine/player.) And below the percent values, the absolute numbers of games are stored.
Additionally all short win games are searched for sacrifices and the statistics for theses sac-games follow below the normal short wins.

The ouput for one engine (full statistic) looks like this:

So, it is easy to see, how much short wins or losses an engine/player has (splitted into7 move-intervals from (0-30) up tp (56-60) moves and with an overall percent score.). And if (and how much) short wins of the engine/player contain a sacrifice.
Mention: The numbers in the "Average game length:"-line are the average length values of all games, the engine has played in the source pgn-file, no matter how long the games were and if they ended before endgame or not. Same for the Overall score and the Overall draw-rate values.
The engine/players in the SGA_full_statistics.txt-file are sorted by: (percent all short wins)-(percent all short draws)-(percent all short losses)
Additionally, the tool writes 3 statistics.txt-files separately for wins/draws/losses:
SGA_wins_statistics.txt, SGA_draws_statistics.txt, SGA_losses_statistics.txt
In there, the engine/players are sorted by (percent all short wins) or (percent all short draws) or (percent all short wins), but, because short wins are a good thing and short draws and losses are not, the short draws and short losses are sorted reversed (smallest number at the top of the file).
And the tool writes a pgn-file with all short wins (up to 60 moves) followed by all short draws: shortgames.pgn (or shortgames_no_endgame.pgn)
And all short win games with a sacrifice are stored in the file short_sac_games.pgn (or short_sac_games_no_endgame.pgn) (sorted top-down: Highest sacs first, lowest behind..).
