RE: Understanding Real-Time Geyser Yield for the WLEO-ETH Uniswap Pool

What if I add later on some more, e.g. because I was too late in powering down LEO and had not yet all available at day 1? How it will be calculated, that one ETH adress has split up the pool between early and some later engagements? Are the days averaged out? Would that in turn mean I screw up my initial pool with the "day 1 premium APY" and so to say dilute it, the more I add later?
