AWS instances - "Max Throughput (MB/s) on EBS" displays wrong values for EBS burstable instances

[stavistavi]

"Max Throughput (MB/s) on EBS" should be 1/8 of "Max Bandwidth (Mbps)" (bits to Bytes division by "8").

Instead, the value seems to be a copy of Baseline Throughput (MB/s)" value.

AWS API is returning correct info:

aws ec2 describe-instance-types --instance-types t3.xlarge --region us-east-2

"EbsInfo": {
                "EbsOptimizedSupport": "default",
                "EncryptionSupport": "supported",
                "EbsOptimizedInfo": {
                    "BaselineBandwidthInMbps": 695,
                    "BaselineThroughputInMBps": 86.875,
                    "BaselineIops": 4000,
                    "MaximumBandwidthInMbps": 2780,
                    "MaximumThroughputInMBps": 347.5,
            "MaximumIops": 15700

where https://instances.vantage.sh/aws/ec2/t3.xlarge returns 86.875 as Max Throughput (MB/s).

Did a quick look into code and I believe the issue is here: https://github.com/vantage-sh/ec2instances.info/blob/00a11b403b44fb1033c3baa101d295812de16008/ec2.py#L395C1-L396C1

@NikhilKumar77777 My point is that there is a wrong information displayed on public website https://instances.vantage.sh/

Not sure how this can be fixed by whatever is in that RAR archive

Also seeing this issue. m5.large and others list the baseline EBS throughput and the max EBS throughput as 81.25MB/s, when the max/burst should be higher, for m5.large should be 593.75MB/s as per https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-optimized.html

Also concur with stavistavi that line 395 of the code is re-referencing 'BaselineThroughputInMBps' again, when it should be using 'MaximumThroughputInMBps'.
