Question: Targetdrift doesn't detect drift when trend is reversed.

[PranavKhedkar]

Hello,
I am using two pandas dataframe:
data1 = {
'Sqft': [600, 700, 800, 900, 1000],
'Price': [235000, 255000, 293350, 321200, 350000]
}
df1 = pd.DataFrame(data1)

data2 = {
'Sqft': [600, 700, 800, 900, 1000],
'Price': [350000, 321200, 293350, 255000, 235000]
}
df2 = pd.DataFrame(data2)

The target here is price. The second dataframe has exact opposite trend as compared to the first. Yet, when I try to use TargetDriftPreset, drift score remains 1 and drift is not detected. Am I doing something wrong?
