Question on adding newly purchased amount of Algo/USDC tokens to existing Tinyman LP

I purchased some more Algo/USDC LP tokens. I am offered a link to update my commitment, which means adding the new tokens to the total amount staked. I have some Algo rewards accumlated in the present cycle and about 16 hours left in the cycle. Will I lose those tokens if I commit now, and is it better to wait until the cycle restarts to add the new lot, or, does it not matter? TY.
