Latency on Real Time Alpaca API

Hello. Good evening. I’m hopeful that this message might reach the developers of Alpaca.

My business partner and I are in the Automated Trading Systems business, we want to be able to stream the ’ NASDAQ : QQQ ’ ETF in real time.

Under the subscription named “Algo Trader Plus” what is the expected latency that exists between the SIP feed and the latency that users under this subscription achieve?

To be more specific, is there an additional amount of latency in the data that I would receive in the Alpaca stream rather than streaming directly from the Nasdaq exchange?

Both seem to offer data feed directly from the SIP, which is the reason for the question.

I would like to add that the trading strategy I am aiming to implement is latency sensitive, which is why any information would be helpful.

Thank you
