Fuel Burn on Our Mainship

I am looking for confirmation on my Fuel burn numbers it seems awfull cheap to run for me but Math is Math Cartouche is a Mainship 390 up in Canada so we only use her 5 Months a year she has a single Yanmar 370Hp with a Koehler 8KW Generator which we have only put 4 hours on since purchase in 2017, Comments would be appreciated as we are planning an extended cruise this year and want to make sure my math is close.
All info is from our Log
2018
Engine Hours at Launch 1705.26
Engine Hours at Haulout1783.11
Engine Hours Used 77.85
Fuel full at Launch
Fuel Purchased $1,557.59 (Average price of $1.70 CDN per Litre
Distance Travelled 509.38 NM
My Calculation is
$3.06 per NM
0.09 Hrs per Litre
0.56 NM to the Litre
average speed was 6.95 Knots
Average RPM was 2070:37

2019 (We did a lot more Locks and River cruising)
Engine Hours at Launch 1783.11
Engine Hours at Haulout 1863.99
Engine Hours used 80.88

Fuel Purchased $1,371.80 (Average price of $2.00 CDN Per Litre
My Calculation is

0.67 NM to the Litre
average speed was 6.03 Knots
Average RPM was 1975:00

Many thanks in advance [/FONT]
