[Speed] Blast Speeds on new account

I switched over to comcast about a month ago because of Blast pricing and speed (30Mbit vs my old 24Mbit). I've noticed that with powerboost, i initially download around 35-36 mbit/s then the speed drops down to 25-26 mbit/s.

Is this normal for the Blast tier, or should it settle closer to 30? I've attached images of signal and bandwidth.

If it was 25Mbit then i was mistaken, and my speeds are fine

i was confused because this is what i saw when i signed up:

The original speed is 25Mbps but with PowerBoost there is an increas of "Up to 30Mbps" i guess depending on servers traffic:

Blast
Original: (25 Mbps/ 4 Mbps)
Power Boost: Down to 30 Mbps + Up to 6 Mbps

I thought PB was uncapped? As in for the first 20 mbps, you could theoretically see 304mbps given the right equipment and system (albeit that's highly unrealistic, 50 is probably more realistic for that small amount of file transfer allowed under PB)....

And it depends on how much unused bandwidth is available on any given node / segment at any given time. Basically it is a reserve / token bucket.

Comcast capped residential PB some time ago. Business appears to be uncapped still though, provided you're on 22/5 or below. 50/10 and up has no PB. I just did a test on my 22/5 connection (was 50/10 until a couple of weeks ago), and it hit 82/22. On 50/10, it was fixed at about 53/11.

I know a few people in my area with D3 modems and Blast, and they get exactly the same PB/non-PB speeds as the OP.

Blast! here (I'm 9 miles north of NW95482, on the same Ukiah CMTS) is 25/4, I get 35/6 with Powerboost.
