I can give a *.pgn file and tools give me the answere of many questions.
All is wonderful ...
But what I missed is to to that round-by-round.
Have a look here:
This one I have to do for FCP Tourney-2022.
And all this for different compatibility reasons with Chessbase PGN and at second I do the same with Chess-Explorer, ChessPad and the "CleanUp" tool by Norm ...
52x Chess-Base PGN
52x Chess-Pad PGN
104 pgn files for 26 rounds I have to create for statistics.

If I give a tools like summary, resultlist, ecolist or others (tools from Norm Pollack) a complex *.pgn file it would be wonderful if I get the statsitics round-by-round .. if I wish ... for every round in new *.txt files.
Same for the cross-tables.
So I have not working on all the *.pgn files for a complex tournament (I lost here many time to do that).
Cross-table:
Somu by Ed can do it, ChessBase database can do it but no program can do it round-by-round with "One" *.pgn file only.
With other words:
A *.pgn file, included are 50 rounds for an example, should be able to give me a cross-table for all 50 rounds and 50 cross-tables for each of the rounds in 50 new *.txt files. Such things I missed here for each of the tools, summary, resultlist, ecolist and so one, the somu tool by Ed and many other tools we have.
Best
