The arithmetic, in full.

One equation, and a proof that the floor can only climb. Drag the withdrawal size and watch it ratchet.

The floor
floor = R / S
Reserve R divided by supply S. The guaranteed value of every token, recomputed on chain each block.
A withdrawal of a tokens
payout = R × a/S × 0.95
You receive your pro-rata slice of the reserve in BNB, less a 5% fee that stays behind.
Reserve and supply, after
R' = R − payout,   S' = S − a
Supply falls by the full a. The reserve falls by only 95% of its share, so the ratio shifts in your favour.
The new floor, and the proof
floor' / floor = (1 − 0.95x) / (1 − x) > 1
where x = a/S. Since 0.95 < 1, this ratio is always above one. Every withdrawal raises the floor. Not by policy, by arithmetic.
