Cloze partial credit evaluation differs between Moodle 4.3 installations when using regular expression patterns

Cloze partial credit evaluation differs between Moodle 4.3 installations when using regular expression patterns

The goal is to ascertain whether Moodle 4.3 evaluates partial credit proportionally for Cloze questions that use regular expression patterns.

The behavior is undocumented, and some sites award full points even when the pattern matches only partially, while others apply reduced credit, creating uncertainty about the intended design versus a regression.

Questions: Does enabling 'Allow partial credit' change the grading outcome for regular expression Cloze items? Are there differences in point allocation between Moodle 4.3 and earlier 4.0 installations? How does the system calculate credit when the pattern matches partially?
