What's your TDS after RO?

I've just changed all my filters and I'm currently flushing the RO, but I'm interested to know what your TDS reading is after DI.
Mines 180 TDS from the tap, don't know what it is after the pre-filters, and it's (so far) a TDS of 10 after the RO.
Yours?

380 ish after RO around 5 then 000 after DI polishes. I also put another sediment filter just before going into pump, I know it won't bring the Tds down but it stops the crap going into the pump. I gotta say as I installed the pump before going into the ro I found the pump to be slightly noisy I had a spare 10" filter so added that before the pump and my pump seems much quieter and hasn't affected the pressure.

I so behind with water production; it's such a boring subject!
I just use a what I think is a standard RO. It gives me about 500 litres a day; but this reduces in Winter a little, but it's not a problem as long as I start the week with a full IBC.
I think I'm changing my RO filters (150 gallon per day) about once-per-year; probably use about 15 litres of resin per year (maybe?) and I reckon my total running costs are under £200.
Does that sound about right for 500 litres per day?

My tap water TDS varies throughout the year but whatever it is I've found that the TDS coming out from the filters is always 5% of the input.
