#  The idea here is, tick is almost a linear function.  We really want a
#  tick_function and compare based on time of day, but this will do for now.
#
#    We can almost determine the typical linear increase of errors 
#     based on time of day.  So here we assume that the linear starts
#     at 6am and increases until 6am the next day.
#
#     NB:  One flaw is that the values are less relevant before noon :}
