the best solution for your timing problem is simply to use one Lomo
spool but several tanks (any plastic basin will do). Fill up five
basins with the chemicals, and five more with water, and you're good
to go. When you get to 55 seconds just lift the spool out, let it
drip five seconds, and into the next soup. This is how we always do
it L'Abominable using exactly these chemicals; and after the third
bath you can turn the lights on anyway.

If you use replenisher after each roll, the R-10 should stay good if
kept in airtight bottles. We don't use kits but we mix D94, D94-R,
D95, D95-R, R10, R10-R, CB2, CB2R, and F5 from raw chemical powders
and they last months when replenished.
