What does the phrase "less creditable" mean?

Question

In the context "It was only later that I pieced together a portrait that was more credible; if less creditable."

Answer 1

According to Google...

 

creditable - adj., (of a performance, effort, or action) deserving public acknowledgment and praise but not necessarily outstanding or successful

 

So I guess in your context, this person had later pieced together a story that was more credible (as in more believable); if less creditable (as in less able to give someone credit with).

EDIT: yeah I guess that's kind of an English faux pas for me to use the root word when explaining its meaning. What I mean to say is "if less creditable (as in less recognized, or less commendable).
