Credit Karma Fudges the "Several Months Later" Math in their First Steps Commercial.

After Conception, the Credit Karma commercial states......."Several Months later"...... and places that voice  over, over Baby's first step.

I am calculating that from Conception probably around 15 to 20 months will elapse for Baby's First Step.  "Several Months later" means anywhere from three months to maybe nine months later, and nine months is being very very generous.

If Credit Karma can't accurately describe in numbers how long between Conception to Baby's First Step, can they be trusted for any other mathematical calculation?
