Our initial experience suggests that the Starlink deprioritized speeds for most people will likely be significantly higher than those quoted by Starlink.

I would expect 50-100Mbps to be Ok for most households (unless there are say more that 5 people, or that there are competitive gamers).  As a comparison, a basic fibre connection is 50Mbps.

Initial reports from users on the deprioritized Standard service plan are that the speeds are similar to the Standard plan. 

Until more is known, I would suggest some caution if frequently engage in Zoom meetings or live in an area with a lot of dishes (eg around Auckland, or north Canterbury).  However I believe that you can revert to the standard plan almost immediately if deprioritised service is insufficient for you.

Test results

We recently initiated our own testing. Below is a graph showing speed test outcomes for a specific dish both before and after transitioning to the Deprioritised plan. The transition took place on March 23rd (indicated by the green line).  On average, the Starlink Deprioritised speed results are around 250Mbps, surpassing the “expected 50-100 Mbps”.  

At this point, I’d suggest that the deprioritised Starlink service may be marginally slower than the standard offering.

This dish is situated in an area characterised by what I would consider a typical density of Starlink dishes. Outcomes may differ in locations such as the greater Auckland area.
