OK it seems that the DSL 1599 plan has already activated last evening.
Posting the speed how it is.
Currently at day from 8am to 6pm, supposed to be 1.344 Mbps or around 166kbps actual. I will post speed now in morning and then later at afternoon for day speed.

Only 7kbps more than promised, but that's still better then less than 222kbps in the evening.
Next I will check speed at night after 12am, Supposed to be 2Mbps or around 248kbps actual from 12am to 8am.
Night 5:30am speed...

Not able to reach 248kbps or above that as I see, So it's not going over between 1.89~1.95 Mbps, 1.95Mbps is also achieved on the fourth test for me but it seems it was a struggle. So it's not going to 2Mbps and over that comfortably, but It's satisfactory. Maybe I need to follow xdsl's advice and fix my line rate.. Will try that tomorrow.
But overall, from whats promised day/evening and night, it should be about 207kbps average for a day and maximum download of 17gb a day & 510 Gb a month.
Off-course speed is not always exact, during the day when it needs to be 166kbps, its doing 180~195kbps, evening its doing 220~230kbps & night when its supposed to do 248kbps+ it can do only 235kbps & 242kbps was achieved only with struggle. Overall fast when its supposed to be slow and not that fast when its supposed to be fast. I'm happy.
If we consider a DVD for a game, software or a HD movie is about 5gb a dvd on average. That would mean I will be able to download about 102 DVD's a month.
Pretty much a big bang for the buck @ 1599 INR + 180 phone rent.
About streaming videos, youtube etc. It runs pretty okay without a noticeable lag, however I have decided to use the VSO downloader that captures streaming video on play and instead starts downloading. This way I don't need to watch streaming stuff smoothly on normal quality, instead can have the 720p & 1080p HD streaming, instead of watching them, have them downloaded in a jiffy and watch from the HD.
I have downloaded about 20-30 HD
music videos and stuff, its able to do 500 MB an hour on ease, so average HD music videos go from 25~100mb, better to use the speed and download HD , watch it from the Hard disk than to watch normal quality streaming on the web. Link to the free trial -->

off-course can get the "educated version" from link-removed.eu or link-removed.se.
