Is this speed doubling work going to clear utilization and if you know, how much extra capacity are they adding to areas (if any?)

Capacity which is been added depends on the area's but they will add more channels which will improve an area with issues, my area had a slow speed issue and they added a 5th downstream as the area has been upgrade and my speeds are solid.

Almost certainly. Power level would drop if your tap point, previusly exclusive to you, had had a splitter put on, each port connected and adding 4 dB per port. It's bad practice, against VM's rules and you should vigorously explore this theory.

Don't know about "against VM's rules", in some areas its perfectly standard practice. Ex-TW areas almost always have shared taps serving dozens of homes via splitters.

Re: Upstream Power Levels Dropped 12dbmv

removing a splitter wont lower the upstream by 12db, unless it was a splitter into a splitter into a splitter!

There shouldnt be splitters in pits but if there are no taps left what are you gonna do? Tell the new customer paying Â£100 a month sorry no can do or stick a splitter in! The problem is so many drops are unidentifiable your never 100% sure if its live. To clear a cab you have to keep all the customers who have a tag and is live and remove the rest and cause alot of upset,
