Cpf & t-bills

Hi,
Need some advice:

​

For the 2 upcoming 6-Month T-Bills in Feb-23 (Announcement Dates = 09-Feb & 23-Feb), is it right to say that buying the 23-Feb is better as it matures 05-Sep & allows us time to roll over & buy T-Bills in same month (Sep-23) to avoid loss of revenue (since CPF not pay in that month) ?

T-Bill / Announcement Date 09-Feb / Maturity Date 22-Aug
T-Bill / Announcement Date 23-Feb / Maturity Date 05-Sep
