[Tagging] Swimming pool lanes

[bkil]

Full disclosure: I'm not of a big swimmer. Could you please elaborate
who this micromapping will serve, who will find use in the marking
that you propose and how stable and dependable it is? Could you share
a mockup tagging combination here that you would put on a given pool
that we would better understand what you need (with any tag you like)?

E.g., 6 lanes in a 4-lane pool - mismatching markings at the pool bottom and mismatching the starting platforms. They may be even of different widths: e.g., one extra wide lane for the aquafitness "joggers", a narrow lane for freestylers, and even a 0.5 m lane for kids learning to swim. The ropes are restored to the original positions for events.
