Consumer status WARN when lag is very low

According to the consumer lag evaluation rules - https://github.com/linkedin/Burrow/wiki/Consumer-Lag-Evaluation-Rules, whenever lag increases, the status is set to WARN:

3. If the consumer offsets are increasing over the window, but the lag either stays the same or increases between every pair of offsets, the consumer is in a WARNING state. This means that the consumer is slow, and is falling behind.

Is there a way to set a threshold for lag in addition to this, my issue is that we trigger alerts on WARNs, but lag is very low - around 200, and clears quickly, whereas we might only want to get a WARN when lag is > 1K or so:

{
"error": false,
"message": "consumer group status returned",
"status": {
"cluster": "local",
"group": "CONSUMER_GROUP",
"status": "WARN",
"complete": true,
"partitions": [
{
"topic": "TOPIC",
"partition": 14,
"status": "WARN",
"start": {
"offset": 112878341,
"timestamp": 1495220705275,
"lag": 11
},
"end": {
"offset": 112882841,
"timestamp": 1495221784466,
"lag": 145
}
},
{
"topic": "TOPIC",
"partition": 23,
"status": "WARN",
"start": {
"offset": 112878287,
"timestamp": 1495220705279,
"lag": 51
},
"end": {
"offset": 112882787,
"timestamp": 1495221784464,
"lag": 185
}
}

Start by reading the Consumer Lag Evaluation Rules wiki page and tracing how the consumer group status response marks partitions and groups as WARN. Define where a configurable lag threshold would apply, then verify that low-lag increases remain below WARN while lag above the threshold still triggers it.
