Using my experience, here is the distribution of maximum weekly turnip prices:
650 or more: 0 weeks (out of 120 weeks = 0.0%)
600 or more: 2 weeks (1.7%)
550 or more: 4 weeks (3.3%)
500 or more: 9 weeks (7.5%)
450 or more: 13 weeks (10.8%)
400 or more: 16 weeks (13.3%)
350 or more: 24 weeks (20.0%)
300 or more: 25 weeks (20.8%)
250 or more: 33 weeks (27.5%)
200 or more: 39 weeks (32.5%)
150 or more: 67 weeks (55.8%)
100 or more: 105 weeks (87.5%)
70 or more: 120 weeks (100.0%)
less than 70: 0 weeks (0.0%)
So, the maximum price is 200 or more about a third of the time.
Also, according to this experience, a price of 500 or more will happen about once every 13 weeks.
Using the same data, here is the distribution by "price period:"
Monday am: 20 weeks (out of 120 weeks = 16.7%)
Monday pm: 0 weeks (0.0%)
Tuesday am: 0 weeks (0.0%)
Tuesday pm: 0 weeks (0.0%)
Wednesday am: 4 weeks (3.3%)
Wednesday pm: 17 weeks (14.2%)
Thursday am: 20 weeks (16.7%)
Thursday pm: 17 weeks (14.2%)
Friday am: 14 weeks (11.7%)
Friday pm: 15 weeks (12.5%)
Saturday am: 10 weeks (8.3%)
Saturday pm: 5 weeks (4.2%)
So, the maximum price occurs on Thursdays almost a third of the time.
