Conjectured upper bound for the mosaic number of a knot

Let $K$ be a knot with crossing number $c$, and let $n$ be its mosaic number.

Mosaic-number upper-bound conjecture. The mosaic number satisfies

$$n\leq c+2.$$

This conjecture is motivated by experimental evidence and proposes a sharper upper bound than the preceding general bound $n\leq 4c+2$.
