There is a graph on the previously quoted page in Telinde that shows the
tensile strength of chromic catgut falling to 60% at one week, 40% at 2
weeks and 0% four weeks and complete absorption by 90 days. The data is
based on Ethicon Research and compares it to plain gut, dexon, vicryl, maxon
and PDS.

I just looked at info on Monocryl and Coated Vicryl on Ethicon's site.
Monocryl is absorbed in 90 to 119 days, and has 30 to 40% of its tensile
strength at 2 weeks.
Coated Vicry is absorbed in 56 to 70 days, and has75% of its tensile
strength at 2 weeks, and 25% at 4 weeks.
I could not find similar data for Chromic, and it is an Ethicon product.
