How to count point below certain threshold.

[ykoba]

I appreciate your help.

I have data set shown below.

ID time NIBP

1 1 89

1 2 90

1 3 78

1 4 87

1 5 88

1 6 89

1 7 90

2 1 77

2 2 88

2 3 90

3 1 99

3 2 100

I would like to count point  where NIBP=<88 for individual ID. I would like to acquire an output like,

ID count

1 3

2 1

3 0

In my actual data set, the number of ID is 18 thousands and the length of the time is different for each ID. 
Thank you very much for your kindness in advance.
