i havnt actually seen the change yet myself but it sounds like its doing a check:

is food negative
if true then
if 25*food > food on hand
then set colour food=red

why not change it to a check for orange if it would be possible to runout with a random event that reduces food or cash by 1/3

obviously 25 random events isnt worth warning about but 1 random even when you sold on private to 0 and are producing less than 3x your consumption is possible

id suggest orange if 2 or 3 bad random events inside 25 turns would cause you to run out of food

on the building page perhaps a check which multiples bpt*buildingcost then gives red if its greater than cash+cashchange

and orange if its greater than cash+randompenaltycashchange

A good player would take into account random events... and not actually spend 25 turns exactly if the max you can survive is 25.

yea, if you plan to spend 25 turns then make sure you have bushels/money for 30+ turns.

Exactly. Further, things like spy production etc, will increase your food expenses every turn so that 25 turns at current rates could really be 24 or 23 to begin with.

why 25? why not 2 or 3? for the first week or two of starting a casher i don't usually have more than 10 turns of food on hand...

i only said 25 because i hear its currently 25

just suggesting that it take into account random factor, not whether 25 is the right amount to start warning at
