Rate limit does not match IB API rate limits?

Hello, it says here that rate limit is 50 messages/3 seconds:

Lean.Brokerages.InteractiveBrokers/QuantConnect.InteractiveBrokersBrokerage/InteractiveBrokersBrokerage.cs

Line 158 in 65cd739

// IB requests made through the IB-API must be limited to a maximum of 50 messages/3 second

however, in IB API documentation it says that the limit is 50 messages/1 second:

Aside from the TWS API's inherent limitation of 50 messages per second implying a maximum of 50 orders per second being sent to the TWS, there are no further API-only limitations. Interactive Brokers however requires its users to monitor their Order Efficiency Ratio (OER) as detailed in the Considerations for Optimizing Order Efficiency IBKB article.

Is it the same rate limit? If so, can we change this limit here, in order to allow more orders sent quicker?

Hey @yul!
Sorry for the delay, we adjusted the rate limit because we were seeing issues, take a look at #29 . There might be room to reduce it but it's risky to undo the change, would require extensive testing many subscriptions/history/orders requests
