Am I dropping out on numerous curiosity by repeatedly reinvesting a 4 week treasury payments bought on Treasury Direct? (because of time between maturation, public sale, and subject dates) : personalfinance

I bought brief time period treasury payments (4 week and eight week) from treasury direct and chosen the choice to reinvest it a number of instances in order that I am not locked in if I want the funds for one thing. I do know the APR rate of interest for shorter phrases are decrease generally. Nevertheless, am I truly dropping much more than the marketed annual price?

It is unclear to me, if the t payments are rolled into the following one seamlessly or if there are gaps between the day the t invoice matures to it truly getting reinvested.
